Question

Mr. Townsend needs to make 13 pairs of butterfly wings for costumes for a pay. Each pair of wings is made with 3/4 yard of fabric. The fabric costs $8 per yard.

You'll apply properties of multiplication in the following questions to find the total cost of the fabric.

2. Multiply the amount of fabric by the price per yard to find an expression for the total cost. Show your work.

Answer 1

1 pair of wings = 3/4 yd. To find the price of one pair of wings, you get 3/4 of $8 which is $6. Mr. Townsend needs 13 wings.
$6/pair x 13 pairs =
$78 for 13 pairs of wings.

Answer 2

13 wings is $78

If each wing is 3/4 a yard and a yard is $8 you do .75x8=$6 so it costs $6 per wing

Then to find how much for 13 wings do 13x6=78
