Explanation:

For his phone service, Ravi pays a monthly fee of $25, and he pays an additional $0.04 per minute of use. The least he has been charged in a month is $73.52. 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.

25 + 0.04m > 73.52

0.04m > 48.52

m > 1,213

in interval notation: (1,213 , ∞)
