Question

For his phone service, Reuben pays a monthly fee of $29, and he pays an additional $0.07 per minute of use. The least he has been charged in a month is $104.04. What are the possible numbers of minutes he has used his phone in a month? Use m for the number of minutes, and solve your inequality for m.

Answer 1

Reuben used his phone for 1,072 minutes.

Explanation:

0.07m + 29 = 104.04

0.07m + 29 -29 = 104.04 -29

0.07m = 75.04

0.07m ÷ 0.07 = 75.04 ÷ 0.07

m = 1,072
