Question

Вследствии двух последовательных снижений ценына одно и то же количество процентов цена кресла снизилась с 800 грн. до 578 грн.На сколько процентов происходило каждый раз снижение цены?

Answer 1

Каждый раз цена снижалась на (800 - 578)/2 = 111 грн. Так, цена каждый раз снижалась на 111/8 = 13,875 %.

Answer 2

Calculation of Percentage Decrease

To calculate the percentage decrease in price, we need to determine the percentage by which the price decreased each time.

Let's assume the initial price of the chair was 800 грн. After the first decrease, the price became 578 грн.

To find the percentage decrease, we can use the following formula:

Percentage Decrease = ((Initial Price - Final Price) / Initial Price) * 100

Let's calculate the percentage decrease for each step:

1. First Decrease: - Initial Price: 800 грн - Final Price: 578 грн

Percentage Decrease = ((800 - 578) / 800) * 100

Calculating this, we find that the first decrease in price was approximately 27.75%.

2. Second Decrease: - Initial Price: 578 грн - Final Price: Unknown (not provided in the question)

Unfortunately, the final price after the second decrease is not provided in the question. Without this information, we cannot calculate the exact percentage decrease for the second step.

Please provide the final price after the second decrease so that we can calculate the percentage decrease accurately.
