Aaron uses the equation y=500+0.2x to determine his weekly paycheck based on his sales volume, where y represents the amount of
lbvjy [14]

Answer:

1050 units

Explanations:

Given the equation y=500+0.2x to determine his weekly paycheck based on his sales volume, where:

y is the amount of his check

x is the number of units he sells each month.

In order to determine the amount of units he would need to sell for his paycheck to be $710, we willl substitute y = 710 into the equation and find the value of x as shown:

y=500+0.2x

710 = 500+0.2x

710-500 = 0.2x

210 = 0.2x

0.2x = 210

Divide both sides by 0.2

0.2x/0.2 = 210/0.2

x = 1050

Hence he would need 1,050 units to sell for his paycheck to be $710
