Question

Kenji buys 3 yards of fabric for 7.47$. Then he realizes that he needs 2 more yards. How much will the extra fabric cost?

Answer 1

the extra fabric will be 4.98 dollars

Answer 2

It will cost $3.98 extra. 

Since 1 yd of fabric is 2.49. Then 5 yds of fabric costs 11.45 (I multiply 2.49 and 5)
11.45 subtract the original price which is 3.98.
