Question

Флакон шампуня стоит 75 рублей. Какое наибольшее число флаконов можно купить на 500 рублей во время распродажи, когда скидка составляет 20%

Answer 1

Решение
1) 100%-20%=80% - составляет цена со скидкой.
2) 75:100%=0,75 (руб.) - составляет 1%.
3) 0,75*80=60 (руб.) - цена одного флакона шампуня со скидкой.
4) 500 руб. = 480 руб. (кратно 60) + 20 руб. (сдача)
480:60=8 (флаконов шампуня) - можно купить во время распродажи.
ОТВЕТ: наибольшее количество шампуней составляет 8 флаконов.

Answer 2

Calculation of the Maximum Number of Shampoo Bottles

To calculate the maximum number of shampoo bottles that can be purchased with a budget of 500 rubles during a sale with a 20% discount, we need to follow these steps:

1. Determine the price of a single shampoo bottle without the discount. 2. Calculate the discount amount. 3. Subtract the discount amount from the original price to get the discounted price. 4. Divide the budget by the discounted price to find the maximum number of bottles that can be purchased.

Let's apply these steps to the given information:

1. The price of a single shampoo bottle is 75 rubles. 2. The discount during the sale is 20%. 3. The discount amount can be calculated by multiplying the original price by the discount percentage: 75 rubles * 20% = 15 rubles. 4. The discounted price can be calculated by subtracting the discount amount from the original price: 75 rubles - 15 rubles = 60 rubles. 5. Finally, we can calculate the maximum number of bottles that can be purchased by dividing the budget of 500 rubles by the discounted price of 60 rubles: 500 rubles / 60 rubles ≈ 8.33.

Since we cannot purchase a fraction of a bottle, the maximum number of shampoo bottles that can be purchased with a budget of 500 rubles during the sale is 8 bottles.

Please note that the calculation assumes that the discount is applied to the price of each individual bottle and not to the total purchase amount.
