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 b. c = 0.46w + 12 c. c = 0.46w + 9.7 d. c = 0.46(w - 5) + 9.7

d. C=0.46(w-5)+9.7

Step-by-step explanation:

the cost of having a package delivered has a base fee of $9.70, that means that independently of the pounds of the package, the cost is always going to be $9.70

Then, there is an additional cost, that just count if the package have more than 5 lbs. Every pound over this 5 lbs, cost $0.46 per pound. So, the additional cost is:

0.46*(w-5)

Where (w-5) are the number of pound that over 5 lbs.

Finally the total cost is the sum of the base cost and the additional cost, that can be written as:

C=0.46*(w-5)+9.7

the answer is 1/4
