The percentage markdown only affects the price of the baseball bat, not the price of the baseball. Therefore, the price of a baseball will remain the same at $12.
What is meant by the term percentage?One technique to express a number as a fraction of 100 is through the use of percentage. It is typically used to denote a percentage or share of a larger whole, and it is frequently written with the sign "%." For instance, a student who obtains an 80 is referred to as having gotten a "80%" or "80%".
Percentages can be used to compare distinct numbers, to assess change over time, or to establish the proportion of a group or population that fits into a specific category. For example, a survey may state that 60% of respondents said "yes" to a certain question, or that the price of a product has grown by 10% in the last year.
How to solve.
If the price of a baseball is marked down by the same percentage as a baseball bat, then the price of a baseball will not change.

Answer:
1. 24 cans/lb x 15,000 lb/trailer = 360,000 cans/trailer
2. Answer will depend on your price per can or per pound. For example, if price is 60 cents per pound: $0.60/lb x 15,000 lb = $9,000
3. 15,000 lbs/trailer / 30 lbs/collector = 500 can collectors/trailer
4. 15,000 lbs/trailer / 800 lbs/bale = 18 complete bales (and 3/4 of another bale)/trailer
5. 24 cans/lb x 800 lb/bale = 19,200 cans / bale
6. 100 bales/boxcar x 800 lbs/bale = 80,000 lb. cans / boxcar
7. 100 bales/boxcar x 19,200 cans/bale = 1,920,000 cans / boxcar

Step-by-step explanation:
The number of newly reported crime cases in a county in New York State is shown in the accompanying table, where x represents the number of years since 2011, and y represents number of new cases. Write the linear regression equation that represents this set of data, rounding all coefficients to the nearest hundredth. Using this equation, estimate the calendar year in which the number of new cases would reach 1141.
Years since 2011 (x) New Cases (y)
0 814
1 825
2 854
3 869
4 947
A linear regression equation that represents this set of data is y = 31x + 799.8.
The calendar year in which the number of new cases would reach 1141 is 2022.
How to write the linear regression equation?In this scenario, the Year since 2011 (x) would be plotted on the x-axis of the scatterplot while the New cases (y) would be plotted on the x-axis of the scatterplot.
On the Excel sheet, you should right click on any data point on the scatterplot, select format trend line and then tick the box to display an equation for the linear regression (line of best fit) on the graph.
By critically observing the scatterplot (see attachment) which models the relationship given in the table for the Year since 2011 (x) and the New cases (y), an equation for the linear regression is given by:
y = 31x + 799.8
Now, we can estimate the calendar year in which the number of new cases would reach 1141:
1141 = 31x + 799.8
31x = 1141 - 799.8
31x = 341.2
x = 341.2/31
x = 11.0
Calendar year = 2011 + 11
Calendar year = 2022.

Piper works in a department store selling clothing. She makes a guaranteed salary of $250 per week, but is paid a commision on top of her base salary equal to 15% of her total sales for the week. How much would piper make in a week in which she made $2050 in sales? how much would piper make in a week if she made xx dollars in sales?.
If a piper will make $2050 in sales in a week than she will get 557.5$ including her commission and salary.
What is commission in money?A sales commission is a payment made to an employee after they successfully complete a task, typically selling a predetermined volume of goods or services. Sales commissions are a common incentive used by employers to boost employee productivity. A commission can be paid instead of or in addition to a salary.
As she makes a guaranteed salary of $250 per week
and paid a commission equal to 15% of her total sales for the week
if she made $2050 in sales in a week
so calculating it 15% commission
=(15x2050)/100

What is slope intercept form ?The slope-intercept form is the way to write a line's equation so that the y-intercept (where the line crosses the vertical y-axis) and slope (steepness) are instantly visible.
The slope intercept form of a straight line equation can be written as :
y = mx + c
Where
m = slope = (change in the y-value) axis's / (change in the value of x in the x axis)
The given line's equation is
y = - x/3 + 5
Slope = - 1/3 as compared to the slope intercept form.
The slope of one line is equal to the negative reciprocal of the slope of the other line if two lines are perpendicular.
As a result, the slope of the line through (3, 4) is 3.
In order to calculate the intercept, we would replace m with 3, x with 3 and y with 4
The equation becomes
4 = 3 × 3 + c
c = -5

Answer:
A.) y = –3x + 4 and y = –3x – 4
Step-by-step explanation:
The first equation of a system of equations is y = -3x + 4 and the second equation is y = -3x - 4.
We can see that both equations have the same slope of -3 and have different y-intercepts of 4 and -4, respectively.
Because the two lines are parallel, they will never intersect and will overlap each other, resulting in an infinite number of solutions.
Therefore, the system of equations y = –3x + 4 and y = –3x – 4 has infinitely many solutions.
