The average cost of four cars was €18,450. what was the total cost of four cars?

€74,600

Step-by-step explanation:

Average cost of cars = Total cost of the cars/number of cars

Given average as €18, 450, number of cars as 4, total cost of the cars= x

18,450 = x/4

Cross multiply

× = €18,650 x 4

x = €74, 600.

I hope this helps.
