Answer 2

Ответ:

234,6 руб.

Решение (в одно действие):

Найдём цену футболки зимой:

$(240*\frac{100\%+15\%}{100\%})*\frac{100\%-15\%}{100\%}=240*1,15*0,85=234,6$ (руб.)

Объяснение:

Сначала цену на футболку увеличили на 15% и она стала равной 115% от первоначальной цены, затем, уменьшили на 15% от летней цены и она стала равной 100%-15%=85%. самое быстрое решение - это увеличить исходную цену в 240 руб. в 1,15 раза, а затем, найти 85% от новой летней цены (решение выше).

Calculation of the Winter Price for the T-shirt

To calculate the price of the T-shirt during winter, we need to consider that the original price of the T-shirt is 240 rubles, and during summer, the price increased by 15%. Then, during winter, the T-shirt was sold with a discount of 15%.

Let's break down the calculation step by step:

1. Increase in price during summer: - The original price of the T-shirt is 240 rubles. - The price increased by 15% during summer. - To calculate the increased price, we multiply the original price by 1 plus the percentage increase: - Increased price = 240 rubles * (1 + 0.15) = 240 rubles * 1.15 = 276 rubles .

2. Discount during winter: - The increased price during summer is 276 rubles. - The T-shirt was sold with a discount of 15% during winter. - To calculate the discounted price, we multiply the increased price by 1 minus the percentage discount: - Discounted price = 276 rubles * (1 - 0.15) = 276 rubles * 0.85 = 234.6 rubles.

Therefore, the T-shirt was sold during winter for approximately 234.6 rubles.

Please note that the calculated price is an approximation, as the exact pricing details may vary depending on the specific store or seller.
