Question

The cost of having a package delivered has a base fee of $10.80. Every pound over 5 lbs cost an additional $0.41 per pound. Write an equation that expresses the cost C in terms of w, the total weight in pounds of a package weighing over 5 lbs. a. C = 10.8w + 0.41 c. C = 0.41(w - 5) + 10.8 b. C = 0.41w + 10.8 d. C = 0.41w + 12.85

Answer 1

c. C = 0.41(w - 5) + 10.8

Step-by-step explanation:

(w - 5) will represent the number of pounds over 5. For example, for a weight of 6 pounds, 6-5 = 1 is the number of pounds over 5.

The cost is $0.41 for each pound over 5, so that cost can be represented by ...

... 0.41(w - 5)

This charge is in addition to the base charge of $10.80, so the total cost will be ...

... C = 0.41(w - 5) + 10.80
