Question

I want to buy a bike in America I decide to get one that cost for $450 the salesman says that if you buy a helmet that cost $20 you get a 20% discount on the bike I accept how much do I pay

Answer 1

Answer:You should pay $380

Explanation:

You bought a helmet that costed $20, so the actual price you had to pay is $470. Since you bought the helmet, the salesmen offered 20% discount on the bike. Therefore 20/100*450 = 360. Total price = price of bike + price of helmet. So 360+20 = 380
