Question

An electric guitar is on sale at 40% off. if the sale price is 179.94 ,what is the original.

Answer 1

Let x = original price
Knowing that multiplying the original price and the discount is the discount price. We formulate:
x(1 - 0.40) = 179.94
x(0.60) = 179.94
x = 179.94/0.60
x = 299.9
That is about 300 of the original price.
