8 A video game that usually costs $50 is on sale for $32.50

finlep [7]

The video game is on 35% discount.

Step-by-step explanation:

Cost of video game = $50

Price on sale = $32.50

Amount of discount = Original price - price on sale

$Amount\ on\ discount = 50-32.50\\Amount\ on\ discount= \$17.5$

Percentage = $\frac{Dicount\ Price}{Original\ Price}*100$

$Percentage=\frac{17.5}{50}*100\\Percentage=\frac{1750}{50}\\Percenatge=35\%$

The video game is on 35% discount.
