PLEASE HELP


For his long distance phone service, David pays a $5 monthly fee plus 9 cents per minute. Last month, David’s long distance bill was $10.58. For how many minutes was David billed?

Answer 1

Subtract the monthly fee:

10.58 -5 = 5.58

Divide the remaining amount by cost per minute:

5.58/ 0.09 = 62

He was billed for 62 minutes.
