Всего ящиков 25 по 3 кг значит 25 умножить на 3 = 75 
Потом 75 - 15 = 60 кг продал 
60 : 3 = 20 ящиков продал 

Answer 3

Solution using System of Equations:

To solve the problem, we can set up a system of equations based on the given information.

Let's denote: - x as the number of boxes sold - y as the total weight of apricots sold in kilograms

We have the following information: 1. The initial number of boxes was 25, and each box contained 3 kilograms of apricots. 2. After selling some boxes, the seller had 15 kilograms of apricots left.

We can express this information in the following equations: 1. x (number of boxes sold) + y (total weight of apricots sold) = 75 (25 boxes * 3 kg/box) 2. y (total weight of apricots sold) = 75 - 15 = 60 kg

Now, we can solve this system of equations to find the values of x and y.

Solving the System of Equations:

We can solve the system of equations using the substitution method.

From the first equation, we can express y in terms of x: y = 75 - x

Substitute this expression for y into the second equation: 75 - x = 60 Solving for x: x = 75 - 60 x = 15

So, the number of boxes sold, x, is 15.

Answer:

Therefore, the seller sold 15 boxes of apricots.
