Bill bought a new cellular phone. His monthly bill will be $34.99 each month which includes 100 minutes of use. Additional minutes will cost $0.23 per minute. Write an equation that represents the cost of the bill C in terms of m, which is the number of minutes used ABOVE the 100 that are included in the base price. a. C = 34.99(m - 100) + 0.23 c. C = 0.23m b. C = 0.23m + 34.99 d. C = 0.23(m - 100) + 34.99 Please select the best answer from the choices provided
