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

solve
\[360+.12x=720+.06x\] for x.

Answer 2

\[360+.06x=720\]
\[.06x=360\]
\[x=\frac{360}{.06}=\frac{36000}{6}=6000\]
