Question

PLEASE ANSWER

All books in a store are being discounted by 40%.

Let x represent the regular price of any book in the store. Write an expression that can be used to find the sale price of any book in the store.

Answer 1

x(1 - .4)

Explanation:

x = regular price.

1 - .4 = .6 = 60%

The sale price is equal to the full price (aka x) minus the discounted price (40% of x = 40/100 times x = .4x)

Therefore sale price = x - .4x or x(1 - .4)
