Vistaprint offers the first 500 business cards for free. Then each additional set of 500 cards cost $9.99.
A. Write an equation that gives the total cosr (in dollars) of cards, C, in terms of the number (in groups of 500) of business cards, b, ordered.
B. Find the cost of buying 3500 business cards.
If the Vistaprint offers the first 500 business card for free and each additional set of 500 card cost $9.99
Part A
The equation that gives the total cost (in dollars) of card C, in terms of the number(in group of 500) of business cards b ordered is C = 9.99×b -9.99
Part B
The cost of buying 3500 business cards is $59.94
The Vistaprint offers the first 500 business cards for free
The cost of each additional set of 500 cards = $9.99
Part A
Consider the total cost of the card = C
Number of business card in group of 500 = b
Then the equation of the total cost of cards
C = 9.99×b -9.99
Part B
Total number of cards = 3500
Number of cards in group of 500 = 3500/500
= 7
The cost of buying 3500 business card = 9.99×7-9.99
= 69.93-9.99
= $59.94
Hence, If the Vistaprint offers the first 500 business card for free and each additional set of 500 card cost $9.99
Part A
The equation that gives the total cost (in dollars) of card C, in terms of the number(in group of 500) of business cards b ordered is C = 9.99×b -9.99
Part B
The cost of buying 3500 business cards is $59.94

Answer:
Second Choice: 8.73b + 171.48 > 381
Step-by-step explanation:
This is a tricky question because the first two choices both represent an inequality that satisfy the conditions
First, let's eliminate obvious wrong choices.
If b represents the number of bags of dog food and one bag costs $8.73, there should be term 8.73b somewhere in the inequality since 8.73b represents the total $ cost of b bags of dog food.
This means we can eliminate the last two choices
Let's deal with the knowns and compute the dollar amounts of each of the products being donated
30 cans of cat food at $0.57 per can = 0.57 x 30 = $17.10
34 cans of dog food at $0.84 per can = 0.84 x 34 = $28.56
18 bags of cat food at $$6.99 per bag = 6.99 x 18 = $125.82
The sum of these is $171.48
She is also donating b bags of dog food at $8.73 per bag = 8.73 x b = $8.73b
So the total cost of the donation =
8,73b + 171.48 which has to exceed 381
So the inequality is
8.73b + 171.48 > 381
Which is the choice you have selected and I believe it is correct
Now, the tricky part comes because if you subtract 171.84 from both sides of the inequality we get
8.73b > 318 - 171.48
Both inequalities are equivalent but we would not write an inequality of the type where the RHS is a mathematical expression. We would instead simplify the right hand side and write it as
8.73b > 209.52 (381-171.48 = 209.52)
I believe the way the question is worded is the LHS should be the $sum of all the donations and the RHS the minimum value.
So the best choice is choice 2: 8.73b + 171.48 > 381

The larger of two numbers is 1 more than 3 times the smaller. Their sum is 65. Find the numbers.
The larger number is 49 and the smaller number is 16.
What are the numbers?The first step is to form a linear expression that represents the larger number.
Let the smaller number be represented with y
The larger number is represented with this linear expression : 1 + 3y
The sum of the two numbers : 1 + 3y + y = 65
Take the following steps to determine the value of the smaller number:
Combine similar terms: 65 - 1 = 3y + y
Add similar terms together: 64 = 4y
Divide both sides by 4: y = 64 / 4
y = 16
Larger number = 1 + 3(16)
1 + 48 = 49

By using the fact that ∠4 and ∠5 add up to 180° and ∠5 = ∠7, we conclude that the measures of the angles are:
∠5 = ∠7 = 56°.
How to find the measures of the angles?For angles formed by the interception between lines meet the following property.
If the angles are one next to the other, the measures add up to 180°.
If not, then the two angles have the same measure.
This means that:
∠5 = ∠7
∠8 = ∠6
And so on.
If the two horizontal lines are parallel, then:
∠5 = ∠1
And we know that:
∠4 + ∠1 = 180°
124° + ∠1 = 180°
∠1 = 180° - 124° = 56°

What is arcsine?The six main inverse trigonometric functions include arcsin. It is the sine function's inverse trigonometric function. The mathematical symbol for arcsin, commonly known as inverse sine, is arcsin x or sin-1x (read as sine inverse x). Sin-1x is not the same as (sin x)-1; that is, sin-1x is not the reciprocal function of sin x. This is an important distinction to make. We may use the six inverse trigonometric functions arccos, arcsin, arctan, arcsec, arccsc, and arccot to calculate angles. Arcsin x calculates the angle that corresponds to the right-angled triangle's perpendicular to hypotenuse ratio. We shall examine the idea of arcsin in this article and determine its formula.

What is a dimensions?
The minimal number of coordinates required to specify any point within a dimensional vector space (or object) is known as the dimension in physics and mathematics. Because only one coordinate is required to specify a point on a line, such as the point at 5 on the a number line, a line is said to have one dimension (1D). Because two coordinates are required to specify a point on a surface, such as the perimeter of a sphere or cylinder, it is referred to as having a dimension of two (2D). For instance, a point on the a sphere's surface requires both a latitude and a longitude to be located. A two-dimensional space just on plane is referred to as a Euclidean space.
The perimeter is 2a+b = 500
b= 500-2a
Max are is A = ab
A= a(500-2a)
= 500a - 2[tex]a^{2}[/tex]

A right pyramid has a surface area of 258 cm2. A right cone has a base radius of 4 cm. The cone and pyramid have equal surface areas. What is the height of the cone to the nearest tenth of a centimetre?
The height of the cone to the nearest tenth of a centimeter is 17.40 cm.
From the given information provided in the question, we can solve this problem by following a few steps.
The surface area of a right pyramid is 258 cm² according to the question.
The surface area of the cone is equal to the surface area of the right pyramid. Therefore the surface area of the cone is also 258 cm².
The surface area of a cone is denoted as ( πrh + πr² ).
Where h is denoted as the height and, r is denoted as the radius of the cone which is 4 cm.
Hence the surface area of the cone is,
SA = (π× 4× h+ π× 4² ) cm²
Now, we can generate an equation, as both represent the value of the surface area of the cone.
(π× 4× h+ π× 4² ) = 258
Or, (12.56h + 39.44) = 258 [ The value of π is 3.14 ]
Or, 12.56h = 258 - 39.44 [ subtracting 39.44 from both sides ]
Or, 12.56h = 218.56
Or, h = 218.56/12.56 [ dividing both sides by 12.56]
Or, h = 17.40
Now, we can conclude that the height of the cone is 17.40 cm.

Based on mathematical operations, the number of people that 10 gallons of punch can serve is 192 persons.
How is the number determined?The number of people can be determined using mathematical operations of multiplication based on converting the gallons to ounces and division.
The number of gallons of punch to serve at the first meeting = 10 gallons
The quantity of punch per serving = 8 ounces
1 gallon = 153.722 ounces
10 gallons = 1537.22 ounces
The persons that can be served 8 ounces from the 10 gallons = 192 (1,537.22/8).
