Answer:
The cost of the car is 26 lei and for ball it is 14 lei respectively
Step-by-step explanation:
The computation of the car and the ball is given below:
Given that
3 balls + 4 cars = 146 lei
3 balls + 7 cars = 224 lei
Based on the above information
3 balls = 146 - 4 cars
3 balls = 224-7 cars
Now
146 - 4cars = 224 - 7 cars
7 cars - 4 cars = 224 - 146
3 cars = 78
1 car = 78: 3 = 26
3 balls = 146 - 4 × 26
3 balls = 146-104
3 balls = 42
a ball = 42: 3 = 14
The cost of the car is 26 lei and for ball it is 14 lei respectively
