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

3 yards = $7.47
2 yards=  $3.73
the total cost of all the fabric would be 11.20

Answer 2

3 yards fabric costs $7.47
1 yard fabric costs $7.47 / 3
2 yard fabric costs $7.47 / 3 * 2
                             = $4.98
so, the extra fabric will cost $4.98
