Question

PLEASE HELP!! Stuart invested $800 in a computer and now makes $5 a page typing research

papers. Let x represent the number of pages Stuart has typed, and let y
represent his profit.

a. Write an equation for y in terms of x.

Answer 1

y = 5x - 800

Explanation:

If x represents the number of pages typed, 5x will represent how much money he earns from typing them, since he gets $5 per page.

Then, 800 needs to be subtracted from this because he spent $800 on the computer.

So, the equation will be y = 5x - 800 to represent his profit.
