Question

Celia’s long distance company
charges $5.95 per month plus
$0.06 per minute. If Celia has
budgeted $30 for long distance, what
is the maximum number of minutes
she can call long distance per month?
A.) 405 minutes
B.) 375 minutes
C.) 400 minutes
D.) 420 minutes

Answer 1

Let c = cost
Let m = number of minutes
c = 5.95 + 0.06m
She has $30 to spend, so the cost must be less than or equal to $30
5.95 + 0.06m <= 30
Can you solve this inequality for m?

Answer 2

well you need to subtract the monthly charge form the cost

30 - 5.95 =

when you have this answer divide it by 0.06... the call cost in dollars

Answer 3

= 400
