Duncan and his family are season ticket holders for their favorite baseball team. Last year, the cost of season tickets was $2,730. This year, the cost is $3,333.80. What was the percent of increase in the cost of season tickets?
Round your answer to the nearest tenth of a percent.
Answer:
10%
Step-by-step explanation:
To find the answer we need to know what percentage of $1030 is $927 and to do this we can multiply 927 by 100 and divide by 1030.
(927(100))/1030
92700/1030
90
so now that we know $927 is 90% of $1030 we can subtract 90 from 100 and it'll give us the percentage decrease. Which is 10%.

Harriet used her credit card to buy a $779 laptop, which she paid off by making identical monthly payments for two and a half years. Over the six years that she kept the laptop, it cost her an average of $0.36 of electricity per day. Harriet’s credit card has an APR of 11.27%, compounded monthly, and she made no other purchases with her credit card until she had paid off the laptop. What percentage of the lifetime cost of the laptop was interest? (Assume that there were two leap years over the period that Harriet kept the laptop, and round all dollar values to the nearest cent.)
a.
7.03%
b.
13.21%
c.
11.27%
d.
6.97%
Answer:
7.03%
Step-by-step explanation:
The percentage of the life time cost which was the interest is; Choice B; 13.21%
Percentage and InterestSince, the APR is compounded monthly at an Annual percentage rate, APR of 11.27%, it follows that;
A = 779(1+0.1127)^(2.5)Hence, the total amount to be paid over the two and half years is; A = $1017.38.
Hence, the interest is given as;
Interest = $1017.38 - $779 = $238.38.The cost of electricity bill at $0.36 per day, (Assuming that there were two leap years over the period).
Cost = 0.36((4×365) +(2×366))Cost = $789.12Hence, the lifetime cost of the laptop is; $789.12 + $1017.38 = $1806.5.
Ultimately, the required percentage is;
($238.38/$1806.5) × 100% = 13.21%Read more on percentages and interest;

The owner of an automotive shop devotes 90% of his workweek to supervising, sales and accounting tasks. In one week, the owner spent 36 hours of his workweek on supervising, sales and accounting tasks. How many hours did he work that week? Group of answer choices
Answer: He worked 40 hours that week.
Step-by-step explanation:
Given : The owner of an automotive shop devotes 90% of his workweek to supervising, sales and accounting tasks. In one week.
Let x = Number of hours he work in a week.
then, Hours for supervising, sales and accounting tasks = 90% of x
As per given ,
[tex]90\%\ of \ x= 36\\\\\Rightarrow\ 0.90x=36\\\\\Rightarrow\ x=\dfrac{36}{0.9}=\dfrac{360}{9}\\\\\Rightarrow\ x=40[/tex]
Hence, he worked 40 hours that week.
metalworker has a metal alloy that is 25% copper and another alloy that is 70%
copper. How many kilograms of each alloy should the metalworker combine to create 50kg of a 52% copper alloy
x = amount (kg) of 25% coper alloy
y = amount (also kg) of 70% copper alloy
Each kilogram of the 25% alloy contains 0.25 kg of copper, while each kilogram of the 70% alloy contains 0.7 kg of copper. When combined, the metalworker ends up with (x + y) kg of an alloy that should consist of 52% copper, so that it contains 0.52 (x + y) kg of copper.
The metalworker wants to make 50 kg of this new alloy, so that
x + y = 50
of which 52%, 0.52 (50 kg) = 26 kg, is copper, so
0.25x + 0.7y = 26
Solve for y in terms of x :
y = 50 - x
Substitute this into the other equation and solve for x :
0.25x + 0.7 (50 - x) = 26
0.25x + 35 - 0.7x = 26
9 = 0.45x
x = 20 → y = 30
12) Two rectangles are similar. The length of small rectangle is 4 and the length of the big
rectangle is 12. If the perimeter of the smaller rectangle is 28, then what is the perimeter
of the larger rectangle
Answer:
84
Step-by-step explanation:
To get from 4 to 12, you multiply with 3.
Everything is 3 times as big in the larger rectangle.
This includes the perimeter.
Example:
small rect 4x10, perimeter 4+4+10+10 = 28
large rect 12x30, perimeter 12+12+30+30 = 84
but also 28x3 = 84
The perimeter of the larger rectangle is 84.
What is perimeter?Its the sum of length of the sides used to made the given figure.
We are given that length of small rectangle is 4 and the length of the big
rectangle is 12. If the perimeter of the smaller rectangle is 28,
The small rectangle
length = 4
perimeter = 28
The big rectangle
length = 12
perimeter = ?
The small rectangle perimeter = 2l + 2w
28 = 2 * 4 + 2 w
28 - 8 = 2w
20 / 2 = w
10 = w
The big rectangle perimeter;
4 w = 10 * 12
w = 120 / 4 = 30
Perimeter = 2*12 + 2*30
= 24 + 60 = 84
The perimeter of the big rectangle is 84.

Every rational number is an integer.
True
False
======================================================
Explanation:
A counter-example could be something like 2/3 which is rational, but not an integer since 2/3 = 0.67 has a fractional or decimal portion to it. An integer is one where its a positive or negative whole number. Zero is also an integer.
Any rational number is a ratio or fraction of two integers. Zero is not allowed in the denominator. Any integer is a rational number since x = x/1, where x is any integer. For example, 9 = 9/1.
Answer:
False
Step-by-step explanation:
Rational numbers include all integers, fractions, or terminating and repeating decimals.
