Question

A computer is on sale for $2400, which is a 40% discount off the regular price. What is the regular price, in dollars?

• A. 6000
• B. 4000
• C. 2000
• D. 1000
• E. None of these

Answer 1

The correct option is B

4000

Let the regular price of the computer be $x$.
$40\%ofx=\frac{40x}{100}$
$x-\frac{40x}{100}=2400$
$\frac{60x}{100}=2400$
$x=4000$
