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

Answer: d. C = 0.23(m – 100) + 34.99 Step-by-step explanation: Let C = X + Y, where C = Cost of the bill in terms of m X = First term of the equation Y = Second term of the equation X = add additional minutes to $ 0.23 …
