Question

Halo me pleeeas... Задача... До расспродажи брюки стоили дешевле пиджака на 60%, и дороже рубашки на 300%. в период расспродажи цена пиджака снизилась на 20%, а цена брюк на 25%. Витя купил пиджак и брюки во время расспродажи. Сколько рубашек он мог купить на ту же сумму, если цена рубашки не изменилась?

Answer 1

До распродажи
х- брюки
х/60*100=10х/6=5х/3- пиджак
х/4- рубашка

После распродажи
5х/3*0,8=4х/3- пиджак
3/4х-брюки
х/4- рубашка

(4х/3+3/4х):х/4=(16х/12+9х/12):х/4=25х/12 *4/х=25/3=8 1/3

Ответ:8 рубашек

Task Analysis

The task involves solving a problem related to the prices of clothing items before and during a sale, and determining the number of shirts that can be bought for the same amount if the price of the shirt remains unchanged.

Given Information

- Before the sale, the pants were 60% cheaper than the jacket and 300% more expensive than the shirt. - During the sale, the price of the jacket decreased by 20% and the price of the pants decreased by 25%. - Vitia bought a jacket and pants during the sale.

Solution Approach

1. Calculate the original prices of the jacket, pants, and shirt. 2. Determine the reduced prices of the jacket and pants during the sale. 3. Calculate the amount spent by Vitia on the jacket and pants during the sale. 4. Use the amount spent to determine the number of shirts that can be bought at the original price.

Calculation Steps

1. Let's assume the original prices of the jacket, pants, and shirt as J, P, and S respectively. 2. From the given information, we have the following equations: - P = J - 60% of J - P = S + 300% of S 3. After the sale, the reduced prices are: - Jacket price = 80% of J - Pants price = 75% of P 4. Let's calculate the amount spent by Vitia on the jacket and pants during the sale. 5. Finally, we'll determine the number of shirts that can be bought for the same amount if the price of the shirt remains unchanged.

Let's proceed with the calculations.
