A washing machine sells for $201 after being discounted by 40 percent. What was the original price of the washing machine?
olga_2 [115]

Step-by-step explanation:

Let original price be x

Price after 40% discount is $201

Therefore

x × 40% = $201

x = 201 ÷ (40/100)

x = 502.5

Therefore, the original price is $502.5

Hope it helps :)
