Question

for his long distance phone service, Hans pays $2 monthly fee plus 12 cents per minute. Last month, hans's long distance bill was $25.04. for how many minutes was han's billed?

Answer 1

Let m stand for number of minutes
.12m+2=25.04
.12m-2=25.04-2
.12m=23.04
.12m÷.12=23.04÷.12
m=192
The number of minutes is 192 minutes.
Hope that helps you!!
