The total cost to five boxes of pasta is $13. There are 12 ounces of pasta in each box. Each box of pasta cost the same amount. What is the maximum number of boxes that can be purchased with $65?

25 boxes

Step-by-step explanation:

If the total cost of 5 boxes is $13, then the cost of one box may be found by dividing the total cost of 5 boxes with the number of boxes

Let the cost of a box be x

x = $13/5

= $2.60

It means that a box of pasta cost $2.60. With $65, the number of boxes that can be purchased

= 65/2.60

= 25 boxes
