Question

You buy a pair of sweats for $22 after a 20% discount. How muchwere the sweats before the discount?

Answer 1

To find the price of the sweats before the discount, take x as this price and make x minus 0.2x (this represents the 20% discount) equal to 22.

$x-0.2x=22$

Now, find x:

$\begin{gathered} x-0.2x=22 \\ 0.8x=22 \\ x=\frac{22}{0.8} \\ x=27.5 \end{gathered}$

The price of the sweats before the discount was $27.5.
