Ответ:

1)24:100=0,24(руб)–один процент от начальной цены.

2)0,24•50=12(руб)–50процентов от начальной цены.

4)36:100=0,36(руб)–один процент от повышенной цены.

5)0,36·50=18(руб)-пятьдесят процентов от повышенной.

Calculating the Cost of Donuts

To calculate the current cost of the donuts, we can follow these steps based on the given information: 1. The price of the donuts was raised twice by 50% each time during the year. 2. Before New Year, the donuts were being sold at half price.

Let's calculate the cost of the donuts at the beginning of the year and then adjust it based on the given information.

Initial Cost of a Donut

At the beginning of the year, the cost of one donut was 24 ropika.

Increase in Price

The price of the donuts was raised twice by 50% each time during the year. Let's calculate the new price after each increase.

1. First increase: 24 ropika + (50% of 24 ropika) = 24 ropika + 12 ropika = 36 ropika 2. Second increase: 36 ropika + (50% of 36 ropika) = 36 ropika + 18 ropika = 54 ropika

Price Before New Year

Before New Year, the donuts were being sold at half price. So, the price became: 54 ropika / 2 = 27 ropika

Current Cost of Donuts

Therefore, the current cost of the donuts is 27 ropika.

Based on the provided information, the current cost of a donut is 27 ropika.
