(A and B) (Monthly fee).................(phone calls) A 4 dollars/ month...........9 cents / min B 4.90 dollars/ month.......7 cents / min Construct an equation that solves the number of calls with the same price" Last edited by skipjack; November 9th, 2019 at 04:27 AM.

Average number of calls per month = 45/(average number of chargeable minutes per call).

The additional 45*2 cents for A per month then matches the 90 cents lower monthly fee.

I don't see a need for x. What I was getting at was average usage = 45 chargeable minutes per month.
