For his long distance phone service, Austin pays a $2 monthly fee plus 12 cents per minute. Last month, Austin's long distance bill was $15.32. For how many

minutes was Austin billed?

Answer 1

Answer: 153

Explanation:

Let x = minutes

0.09x = 13.77

x = 13.77 ÷ 0.09 = 153

He was billed for 153 minutes
