Problem Analysis

We are given that 4 identical albums cost 28 rubles and 3 identical sets of paints cost 27 rubles. We need to determine the cost of one set of paints compared to one album.

Solution

Let's assume the cost of one album is x rubles and the cost of one set of paints is y rubles.

From the given information, we can set up the following equations:

Equation 1: 4x = 28 (since 4 identical albums cost 28 rubles) Equation 2: 3y = 27 (since 3 identical sets of paints cost 27 rubles)

To find the cost of one set of paints compared to one album, we need to find the value of y in terms of x.

Solving the Equations

Let's solve Equation 1 for x: 4x = 28 Dividing both sides by 4: x = 7

Now, let's solve Equation 2 for y: 3y = 27 Dividing both sides by 3: y = 9

Answer

Therefore, one set of paints costs 9 rubles, which is 2 rubles more expensive than one album (7 rubles).
