<h3>Answer:</h3>
c. C = 0.41(w - 5) + 10.8
<h3>Explanation:</h3>
(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
