Question

В магазин привезли 240 курток.Часть курток продали в первый же день,на следующий день продали ещё 25 курток.После этого осталось продать в 3 раза больше курток чем в продали за 2 дня.Сколько курток продали в первый день?

Answer 1

х+25+3*(х+25)=240

х+25+3х+75=240

4х+100=240

4х=240-100

4х=140

х=140/4

х=34(к)-прдали в 1 день

3*(35+250)=180(к)-продали за 3 день

Answer 2

пусть в первый продали х курток, во второй по условию 25 тогда  в третии 3(х+25)

х+25+3*(х+25)=240

х+25+3х+75=240

4х+100=240

4х=240-100

4х=140

х=140/4

х=35 курток продали в первый день продали

3*(35+25)=180курток продали в третии

Answer 3

Calculation of Jackets Sold on the First Day

To determine the number of jackets sold on the first day, we need to analyze the information provided.

According to the question, a total of 240 jackets were delivered to the store. Some jackets were sold on the first day, and an additional 25 jackets were sold on the following day. After these two days, there were still three times as many jackets left to sell as the number of jackets sold in the first two days.

Let's break down the information step by step:

1. Total number of jackets delivered: 240.

2. Number of jackets sold on the first day: Unknown.

3. Number of jackets sold on the second day: 25.

4. Number of jackets left to sell after the first two days: 3 times the number of jackets sold in the first two days.

To find the number of jackets sold on the first day, we can set up an equation:

(Number of jackets sold on the first day) + (Number of jackets sold on the second day) = 3 * (Number of jackets sold on the first two days)

Let's solve the equation:

Let x be the number of jackets sold on the first day.

x + 25 = 3 * (x + 25)

Simplifying the equation:

x + 25 = 3x + 75

Subtracting x from both sides:

25 = 2x + 75

Subtracting 75 from both sides:

-50 = 2x

Dividing both sides by 2:

x = -25

The solution to the equation is x = -25. However, this doesn't make sense in the context of the problem, as we cannot have a negative number of jackets sold. Therefore, there seems to be an error or inconsistency in the information provided.

Without further clarification or additional information, it is not possible to determine the exact number of jackets sold on the first day.
