Question

a cell phone company offers two different plans. In one plan there is a monthly fee of 40$ and charges .25 per minute. On the other, there is a monthly fee of 25 dollars and charges .40 per minute. When are the times equal?

Answer 1

Explanation:

40 + 0.25t = 25 + 0.40t

15 = 0.15t

t = 100

Costs are the same at 100 minutes.
