Question

Company A rents copiers for a monthly charge of $360 plus 12 cents per copy. Company B rents copiers for a monthly charge of $720 plus 6 cents per copy. What is the number of copies above which Company A's charges are the higher of the two?

Answer 1

It's the point where the two straight line graphs intercept , which you can solve with an equation. Here is how your equation is suppose to look like:
360+0.12=720+0.06x at the equal point where x is the number of copies
Now take 360 from each side.
