Shari bought 2 1/2 yard of fabricfor $7.99 per yard. she used 3/4 of fabric to make decorative pillows. how much money could shari have saved by only buying the amount of fabric that she used? write your answer in dollars and round to the nearest tenth.

First, calculate how much Shari paid in total for 2.5 yards of fabric. Since each yard costs $7.99, you would multiply the number of yards Shari bought by the price per yard:
7.99×2.5=19.975, which rounds to $19.98

Then, calculate how much fabric Shari actually used:
(3/4)×2.5 yds= 1.875 yards

Next, calculate how much Shari would have paid if she only bought the amount of fabric that she used (1.875 yards):
7.99×1.875=14.98125, which rounds to $14.98

Lastly, to find the amount Shari could have saved, subtract $14.98 from the amount Shari actually paid, $19.98:
19.98-14.98=5. 
So, the final answer would be that Shari could have saved $5.
