Question

Johnny wants to ship a package to his friend. A shipping company charges $2.49 for the first pound and $1.24 for each additional pound. If it cost Johnny $11.17 to ship the package, how much did his package weigh?

a) 3 pounds
b) 4 pounds
c) 5 pounds
d) 6 pounds

Answer 1

To determine the weight of Johnny's package, we set up an equation using the cost of the first pound, the cost of each additional pound, and the total cost of shipping. Solving the equation, we find that the package weighs 7 pounds.

Step-by-step explanation:

To find out how much Johnny's package weighs, we need to determine the additional pound(s) he was charged for. Let's say he was charged for x additional pound(s). So the total weight of the package would be 1 pound (the first pound) plus x pounds (the additional pound(s)).

Based on the information given, we know that the cost of the first pound is $2.49 and the cost for each additional pound is $1.24. We also know that the total cost of shipping the package is $11.17.

Setting up an equation, we can write:
2.49 + 1.24x = 11.17.

Solving this equation, we find that x = 6. So there were 6 additional pounds. Therefore, the total weight of Johnny's package is 1 pound (the first pound) + 6 pounds (the additional pounds) = 7 pounds.
