Question

A teacher works for a textbook company during the summer. She makes $35 per page to write the material and $25 per page to type it. The teacher would like to earn at least $3200, but does not want more than 120 pages of work. Let "x" represent the number of pages written and "y" represent the number of pages typed. Write a system of inequalities to represent this situation.

Answer 1

$35 x + $25 y ≥ $3200 x ≤ 120

Explanation:

Because she needs to write before type the page, so that y≤x

∴ x≤120

$35 x + $25 y ≥ $3200 x ≤ 120
