Question

It takes 45 inches of ribbon to tie each bow. Each roll of ribbon holds 10 yards and costs $4.00. At that rate, how much would it cost for enough ribbon to tie 40 bows?

Answer 1

To tie 40 bows using ribbon that requires 45 inches per bow, one needs 5 rolls of ribbon at $4.00 each, totalling $20.00.

Step-by-step explanation:

To calculate the cost of enough ribbon to tie 40 bows, we first need to determine how much ribbon is required in total and then how many rolls of ribbon we need to purchase.

Since it takes 45 inches of ribbon to tie each bow, and we need to tie 40 bows, we multiply 45 inches by 40 bows to get the total amount of ribbon needed in inches:

45 inches/bow × 40 bows = 1800 inches total

There are 36 inches in a yard, so we convert the total inches to yards:

1800 inches ÷ 36 inches/yard = 50 yards of ribbon

Each roll contains 10 yards of ribbon, so we need 50 yards ÷ 10 yards/roll = 5 rolls of ribbon.

Since each roll costs $4.00, the total cost for 5 rolls is calculated as follows:

5 rolls × $4.00/roll = $20.00

Therefore, the total cost for enough ribbon to tie 40 bows is $20.00.
