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?
Thoughts? Step-by-step reasoning:
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.
Thus, the answer is 9.
