Solve the problem.Bill bought a new cellular phone. His monthly bill will be $35.99 each month which includes 100 minutes of use. Additional minutes will cost $0.20 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 = 0.20m B. C = 0.20m + 35.99 C. C = 35.99(m - 100) + 0.20 D. C = 0.20(m - 100) + 35.99
