Cost reduction

Two MP3 players whose prices were equal initially were discounted, the first by 20%, the second by 35%. After the price reduction, their prices were 750 CZK different. What was each player's original price?

Correct answer:

a =  5000 Kc

Step-by-step explanation:


a·(1-20/100)-a·(1-35/100) = 750

15a = 75000


a = 75000/15 = 5000

a = 5000
