Carly is overnight shipping some fresh-baked cookies to her grandma. The shipping cost is equal to a flat $5.00 fee plus $0.80 per pound of weight. If the package weighs 5 pounds, how much does Carly pay for shipping?
First calculate the weight-based charge by multiplying the package's weight in pounds by the price per pound: 5 pounds * $0.80/pound = $

4.00.
Then add the weight-based charge to the flat fee to find the total cost: $4.00 + $5.00 = $

9.00.
