Answer 2

It's original price as $18.5.

Explanation:

This question can be solved using a rule of three.

$12.95 per square yard is 30% off its original price.

This means that $12.95 is 100-30 = 70% = 0.7 of the original price. How much is 100% = 1?

x - 1

12.95 - 0.7

`0.7x = 12.95`

`x = (12.95)/(0.7)`

`x = 18.5`

It's original price as $18.5.
