Question

a sporting goods store charges $30 for 12 cans of tennis balls and $45 for two boxes of golf balls. a coach orders 100 cans of tennis balls and 5 boxes of golf balls. how much will the coach pay for the tennis and golf balls?

Explanation:

Step1: Find cost per tennis ball can

To find the cost of one can of tennis balls, we divide the total cost by the number of cans. The store charges $30 for 12 cans, so the cost per can is $\frac{30}{12}$.
$\frac{30}{12} = 2.5$ dollars per can.

Step2: Find cost per golf ball box

To find the cost of one box of golf balls, we divide the total cost by the number of boxes. The store charges $45 for 2 boxes, so the cost per box is $\frac{45}{2}$.
$\frac{45}{2} = 22.5$ dollars per box.

Step3: Calculate cost for 100 tennis ball cans

The coach orders 100 cans of tennis balls. Since each can costs $2.5, the total cost for tennis balls is $100\times2.5$.
$100\times2.5 = 250$ dollars.

Step4: Calculate cost for 5 golf ball boxes

The coach orders 5 boxes of golf balls. Since each box costs $22.5, the total cost for golf balls is $5\times22.5$.
$5\times22.5 = 112.5$ dollars.

Step5: Calculate total cost

To find the total amount the coach pays, we add the cost of tennis balls and golf balls. So we add 250 and 112.5.
$250 + 112.5 = 362.5$ dollars.

Answer:

The coach will pay $362.5$ dollars.
