Tracy is taking advantage of a 25% off sale to buy a new coat. If the coat's sale price is $135, what was the original cost?

Answer 1

Let the original cost of the coat be "x".

At a 25% discount, Tracy would pay 75% of the original price:

0.75x = 135

Divide both sides by 0.75 to solve for x:

x = 180

Therefore, the original cost of the coat was $180.
