A telephone company charges a fee of $29.99 per month for basic local service. A fee of $4.95 per month is added for customers wanting up to 500 minutes of long distance at $0.04 minute.
a. Write a cost function to determine the amount a customer with the local and long distance plans would be charged that is based on the number of long distance minutes used each month.
b. Use the function you’ve written to determine how much a customer making 345 minutes worth of long distance calls would be charged for the month.
Homework Equations
The Attempt at a Solution
C= p+f+(.04x)
C=29.99+ 4.95+ (.04x)
C=29.99+ 4.95+ (.04x345)
C= 29.99+ 4.95+ 13.80
C= 48.74
Not sure if there needed to be an x after the C or not.
