Bill bought a new cellular phone. His monthly bill will be $32.99 each month which includes 100 minutes of use. Additional minutes will cost $0.19 per minute. Write a linear model that represents the amount of the bill, C, based on the total number of minutes, m, the phone is used in a month. Assume m ≥100 minutes.
a.
C = 0.19m + 32.99
c.
C = 0.19m
b.
C = 32.99(m - 100) + 0.19
d.
C = 0.19(m - 100) + 32.99
