For his phone service, Alonzo pays a monthly fee of

$18

, and he pays an additional

$0.05

per minute of use. The least he has been charged in a month is

$75.95

.

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

This would be your equation (method of solving for number of minutes):

m = 75.95 - 0.05 (m)

f = $18 monthly fee

m = number of minutes used

explanation of above equation:

number of minutes equals, the total amount, subtract the monthly fee. then take the total of that equation and divide it by 0.05, to get the number of minutes (m).

I cannot solve the equation but I do know it is an 18 dollar monthly fee.
