A phone company charges a $4 monthly service fee and $0.25 for every minute of long-distance call time. If your telephone budget is $9.48, what is the maximum number of minutes of long-distance calls you can make? (Round your answer down to the nearest minute.)

Answer :

Assuming it's the amount of minutes you can call per month:
9.48 - 4 is 5.48
5.48 ÷ 0.25 is 21 point something. Since you have to round down, 21 minutes is the Max amount of time you can call.

The maximum number of minutes of long-distance calls that the person can make is 22 minutes.

Let the number of minutes be represented by m.

Based on the information given, the equation to solve the question will be:

4 + 0.25m = 9.48

Collect like terms

0.25m = 9.48 - 4

0.25m = 5.48

m = 5.48 / 0.25

m = 21.92 = 22

Therefore, the number of minutes is 22 minutes.
