Answer 2

Problem Analysis

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

Solution

Let's assume that 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 form the following equations: - 4x = 28 (equation 1) - 3y = 27 (equation 2)

To find the value of x and y, we can solve these equations simultaneously.

Solving the Equations

Let's solve equation 1 for x: - Divide both sides of equation 1 by 4: 4x/4 = 28/4 - Simplifying, we get: x = 7

Now, let's solve equation 2 for y: - Divide both sides of equation 2 by 3: 3y/3 = 27/3 - Simplifying, we get: y = 9

Answer

Therefore, one album costs 7 rubles and one set of paints costs 9 rubles. To find how much more expensive one set of paints is compared to one album, we subtract the cost of one album from the cost of one set of paints: 9 - 7 = 2 rubles.

Questions Answered

The solution to the given problem answers the following questions: 1. How much does one album cost? 2. How much does one set of paints cost? 3. How much more expensive is one set of paints compared to one album?

Solution Verification

Let's verify the solution using the given information: - 4 albums cost 28 rubles, so one album costs 28/4 = 7 rubles. This matches the value we obtained in the solution. - 3 sets of paints cost 27 rubles, so one set of paints costs 27/3 = 9 rubles. This also matches the value we obtained in the solution.

Therefore, the solution is correct.
