<h3>Answer:  c = 0.0325d</h3>

==========================================================

Explanation:

For each row, divide the earnings over the sales.

  • In row 1, we have 22/673 = 0.0327 approximately
  • In row 2, we have 37/1298 = 0.0285 approximately
  • In row 3, we have 101/3277 = 0.0308 approximately
  • In row 4, we have 150/5180 = 0.0290 approximately

All of these decimal values have the following conversions to percentages

  • 0.0327 = 3.27%
  • 0.0285 = 2.85%
  • 0.0308 = 3.08%
  • 0.0290 = 2.90%

If we add up those percentages and divide by 4, we get the average percentage

(3.27+2.85+3.08+2.90)/4 = 3.025

So the average percentage of these four is 3.025%

So for instance, if you made $1000 in sales, then 0.0325*1000 = 32.50 would be the estimated earnings.

A good estimate in my opinion is the equation c = 0.0325d since 3.025% converts to the decimal form 0.0325

Another method you could use is linear regression to help estimate. Though this method is a lot more complicated involving many more steps. It's better to use technology (eg: graphing calculator) if you go this route. The linear regression line is approximately y = 0.02896x + 2.00732; we can see the slope 0.02896 isn't too far off from 0.0325. Other forms of regression are possible as well.

Complete the diagram to find 430 percent of 90
ludmilkaskok [199]

The easiest way to find percent is to make the percent into a decimal and multiply. Move the decimal to places to the left to make 4.30, and multiplied by 90 equals 387, so 430 percent of 90 is 387.

One leg of a right triangle is 28 inches longer than the other leg, and the hypotenuse is 52 inches. Find the lengths of the leg
katovenus [111]

Step-by-step explanation:

Let x represent the missing sides measurement.

x+x+28=52

combine like terms

2x + 28 = 52

subtract 28 from both sides

2x + 28 = 52

     - 28  - 28

2x = 24

divide both sides by 2

x = 12

plug it back in

one leg is 12 inches

the other leg is 40 inches
