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 $0.44 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 = 0.44w + 11.9 B. C = 9.7w + 0.44 C. C = 0.44w + 9.7 D. C = 0.44(w - 5) + 9.7
