Question

Your weekly base salary is $150.You earn $20 for each cell phone that you sell.

write and solve an inequalitiy that represents the number of cell phones you must sell to make at least $750 a week.

Answer 1

Explanation:

Let the number of cell phones be represented by X;

Price per cell phone = $20

$150 is a constant

Minimum goal per week = $630

The inequality will be;

150 + 20X 630

20X 630 -150

20X 480

Divide both sides by 20 to solve for X;

X 480/20

X 24

Therefore, you must sell at least 24 cell phones.
