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).
