Personalul unei gradinite a cumparat 3 mingi si 4 masinute, pentru care a platit 146 de lei. dupa un timp, s-au mai cumparat la acelas pret 3 mingi si 7 masinute, in valoare de 224 de lei. cat costa o masinuta?dar o minge?

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
