Problem Analysis

We are given two equations: 1. Six plush toys and one packet of juice cost a total of 180 rubles. 2. Six plush toys and four packets of juice cost a total of 270 rubles.

We need to find the cost of two packets of juice and three plush toys.

Solution

Let's solve the problem step by step.

Let's assume the cost of one plush toy is x rubles and the cost of one packet of juice is y rubles.

From the first equation, we can write the following equation: 6x + y = 180 From the second equation, we can write the following equation: 6x + 4y = 270 To find the cost of two packets of juice and three plush toys, we need to find the value of 2y + 3x.

To solve the system of equations, we can use the method of substitution or elimination. Let's use the method of elimination.

Multiplying equation by 4 and equation by 1, we get: 24x + 4y = 720 6x + 4y = 270 Subtracting equation from equation we get: 18x = 450

Dividing both sides by 18, we get: x = 25

Substituting the value of x into equation we get: 6(25) + y = 180 150 + y = 180 y = 30

Now we have the values of x and y. Let's calculate the cost of two packets of juice and three plush toys.

2y + 3x = 2(30) + 3(25) = 60 + 75 = 135

Therefore, the cost of two packets of juice and three plush toys is 135 rubles.

Answer

The cost of two packets of juice and three plush toys is 135 rubles.
