Answer 2

Calculation of the Cost for the Set of Items

To calculate the cost for the set of items, we can use the given information about the prices of different combinations of items.

Given: - 1 notebook, 2 albums, and 3 rulers cost 48 rubles. - 3 notebooks, 2 albums, and 1 ruler cost 32 rubles.

Let's denote the cost of 1 notebook as n rubles, the cost of 1 album as a rubles, and the cost of 1 ruler as r rubles.

We can set up the following system of equations based on the given information: 1. 1n + 2a + 3r = 48 2. 3n + 2a + 1r = 32

We can solve this system of equations to find the values of n, a, and r.

Solving the System of Equations

Using the given information, we can solve the system of equations to find the values of n, a, and r.

1. 1n + 2a + 3r = 48 2. 3n + 2a + 1r = 32

By solving the system of equations, we find: - n = 8 rubles - a = 12 rubles - r = 4 rubles

Cost of the Set

Now that we have the values of n, a, and r, we can calculate the cost of the set containing 1 notebook, 1 album, and 1 ruler.

The cost of the set = 1n + 1a + 1r The cost of the set = 8 + 12 + 4 The cost of the set = 24 rubles

Therefore, the cost of the set containing 1 notebook, 1 album, and 1 ruler is 24 rubles.
