Answer 3

Calculating the Cost of the Magazine and Newspaper

To solve this problem, we can set up a system of equations. Let's denote the cost of the magazine as m and the cost of the newspaper as n. We are given two pieces of information: 1. The magazine is more expensive than the newspaper by 25 rubles: m = n + 25 2. Together, the magazine and the newspaper cost 43 rubles: m + n = 43

Solving the System of Equations

We can use the first equation to express m in terms of n and then substitute this expression into the second equation to solve for n.

From the first equation, we have: m = n + 25

Substituting this into the second equation: (n + 25) + n = 43 Simplifying: 2n + 25 = 43 Subtracting 25 from both sides: 2n = 18 Dividing by 2: n = 9

Calculating the Cost of the Magazine and Newspaper

Now that we have found the cost of the newspaper (n = 9), we can use the first equation to find the cost of the magazine: m = 9 + 25 m = 34

So, the newspaper costs 9 rubles and the magazine costs 34 rubles.

Therefore, the newspaper costs 9 rubles and the magazine costs 34 rubles.
