Question

Фирма "Карлсон" продала в первый день 900 штук мороженого "Карлсаунти", что составляет 30% мороженого, проданного ею за второй день. За третий день фирма продала 5/13 от количества мороженого, которое у неё купили за первые 2 дня. Сколько мороженого продала фирма за все 3 дня? Сколько денег фирма получила от покупателей за эти три дня, если одно мороженое стоит 12 руб. 50 коп.?

Answer 1

900*100:30=3000 шт------- продали во второй день

3000+900=3900 шт--------- продали за два дня

3900*5/13=1500 шт-------- продали в третий день

1500+3900=5400 шт --------продали за три дня

5400*12,50=67500 руб------ фирма получила от покупателей за 3 дня.

Answer 2

To answer your question, let's break it down step by step.

Given Information:

- On the first day, the company "Karlsun" sold 900 units of "Karlsaunti" ice cream, which represents 30% of the ice cream sold by the company on the second day. - On the third day, the company sold 5/13 of the ice cream that was purchased during the first two days. - The price of one ice cream is 12 rubles and 50 kopeks.

Calculation:

1. Let's find out how much ice cream the company sold on the second day. Since the ice cream sold on the first day represents 30% of the ice cream sold on the second day, we can set up the following equation:

900 = 0.3 * X

Solving for X, we find that the company sold X = 900 / 0.3 = 3000 units of ice cream on the second day. [[1]]

2. Now, let's calculate how much ice cream the company sold on the third day. The company sold 5/13 of the ice cream purchased during the first two days. Let's denote the total ice cream purchased during the first two days as Y. We can set up the following equation:

Y * (5/13) = Z

Solving for Z, we find that the company sold Z = Y * (5/13) units of ice cream on the third day.

3. To find the total ice cream sold over the three days, we need to sum up the ice cream sold on each day:

Total ice cream sold = 900 (first day) + 3000 (second day) + Z (third day)

4. Finally, let's calculate the total amount of money the company received from customers over the three days. Since one ice cream costs 12 rubles and 50 kopeks, we can multiply the total ice cream sold by the price per ice cream:

Total money received = (900 + 3000 + Z) * (12 rubles + 50 kopeks)

Answer:

The company "Karlsun" sold a total of 900 + 3000 + Z units of ice cream over the three days. The total amount of money the company received from customers over the three days is (900 + 3000 + Z) * (12 rubles + 50 kopeks).

Please note that we still need to calculate the value of Z to determine the exact quantities of ice cream sold on the third day and the total amount of money received by the company.
