Answer:
1. 8.5 yards.
2. $42.5
Step-by-step explanation:
We have been given that Sue buys 5 pieces of fabric. Each piece is yards long.
1. To find the total length of fabric bought by Sue we will multiply length of each fabric piece by 5.
Therefore, Sue bought 8.5 yards of fabric.
2. 1 yard of fabric costs $5.
So 8.5 yards of fabric will cost : 5*8.5
Therefore, the cost of total fabric bought by Sue is $42.5.
