Answer:

880 minutes

Step-by-step explanation:

cost = 0.05(per minute) + basic fee

y = 0.05x + 15

59 = 0.05x + 15

subtract 15

44 = 0.05x

divide by 0.05

x = 880

Answer:

880 phone calls.

Step-by-step explanation:

His phone bill was 59 dollars.  The phone company charged him 15 dollars for a basic fee, so that is $59-$15 which equals $44.

Since every call costs $0.05, you need to do $44 divided by $0.05 to get the amount of phone calls he did.

$44 divided by $0.05= 880, so Joe made 880 phone calls.
