Answer 2

Let's use algebra to solve this problem. Let's assume the cost of one balloon is "x" rubles.

According to the information given: 4 balloons cost 15 rubles more than 1 balloon, so the cost of 4 balloons is x + 15 rubles.

Now we can set up an equation:

4x = (x + 15)

Let's solve for "x":

4x = x + 15

Subtract "x" from both sides:

3x = 15

Now, divide both sides by 3 to find the value of "x":

x = 15 / 3

x = 5

So, one balloon costs 5 rubles.
