Find original price

Question

After a 80% reduction, you purchase a new DVD player on sale for $108. What was the original price of the DVD player?

Answer 1

X = current selling price

 

Y= Original Price

Discount on original Price = 80%

Discount = 80% of Y = 80Y/100 

X = Y - Discount = Y - 0.8 Y = 0.2 Y = 108 ( as given )

 

Y = 108/0.2 = 540

Original price = $ 540
