Solve the problem. The cost of having a package delivered has a base fee of $9.70. Every pound over 5 lbs cost an additional $0.46 per pound. Write a linear model that represents the cost, C, for the total weight, w, in pounds of the package. Assume w 5 lbs. a. C = 9.7w + 0.46 c. C = 0.46w + 9.7 b. C = 0.46w + 12 d. C = 0.46(w - 5) + 9.7 Please select the best answer from the choices provided
