Problem Statement

Утром в классе было 780 грн. За день выдали 540 грн, а приняли 430 грн. Сколько денег стало в кассе в конце дня? Решить задачу разными способами.

Solution

To solve this problem, we can use two different approaches: the direct method and the balance method.

Direct Method

The direct method involves adding the amount received and subtracting the amount given to find the final balance in the cash register.

1. Start with the initial amount in the cash register: 780 грн. 2. Add the amount received: 780 грн + 430 грн = 1210 грн. 3. Subtract the amount given: 1210 грн - 540 грн = 670 грн.

Therefore, the final balance in the cash register at the end of the day is 670 грн.

Balance Method

The balance method involves calculating the net change in the cash register by subtracting the amount given from the amount received.

1. Calculate the net change: 540 грн - 430 грн = 110 грн. 2. Add the net change to the initial amount: 780 грн + 110 грн = 890 грн.

Therefore, the final balance in the cash register at the end of the day is 890 грн.

Both methods yield the same result, so the final balance in the cash register at the end of the day is 670 грн or 890 грн.

Conclusion

The final balance in the cash register at the end of the day can be calculated using either the direct method or the balance method. In this case, the final balance is 670 грн or 890 грн, depending on the method used.
