Problem Analysis

Three friends, Vasya, Kolya, and Vitya, want to buy a football ball that costs 150 rubles. Vasya has 63 rubles, Vitya has 55 rubles, and Kolya has 19 rubles less than Vitya. The question is whether the friends can buy the ball with their combined money.

Solution

To determine if the friends can buy the football ball, we need to calculate the total amount of money they have and compare it to the price of the ball.

Let's calculate the total amount of money the friends have:

- Vasya: 63 rubles - Vitya: 55 rubles - Kolya: 19 rubles less than Vitya

To find out how much money Kolya has, we subtract 19 rubles from Vitya's amount:

Kolya's money = Vitya's money - 19 rubles

Now, let's calculate the total amount of money the friends have:

Total money = Vasya's money + Vitya's money + Kolya's money

Finally, we compare the total amount of money with the price of the football ball to determine if the friends can buy it.

Calculation

Let's calculate the total amount of money the friends have:

- Vasya: 63 rubles - Vitya: 55 rubles - Kolya: Vitya's money - 19 rubles

Kolya's money = 55 rubles - 19 rubles = 36 rubles

Total money = Vasya's money + Vitya's money + Kolya's money = 63 rubles + 55 rubles + 36 rubles

Total money = 154 rubles

Conclusion

The total amount of money the friends have is 154 rubles. Since the price of the football ball is 150 rubles, the friends have enough money to buy the ball.

Therefore, the friends can buy the football ball.
