The price of a car is 500.000 naira. If a discount of 5% is allowed on each car, how much is paid for 5 such car?

First, we calculate the discount on one car:

Discount = 5% of 500,000 = 0.05 x 500,000 = 25,000 naira

So, the discounted price of one car = 500,000 - 25,000 = 475,000 naira

Therefore, the total amount paid for 5 cars = 5 x 475,000 = 2,375,000 naira

So, the total amount paid for 5 cars after a 5% discount is 2,375,000 naira.
