Answer 2

Problem Analysis

We are given that three cans of paint cost 360 rubles, and a brush is five times cheaper than a can of paint. We need to determine how many brushes can be purchased with the same amount of money.

Solution

Let's start by finding the cost of one can of paint. We know that three cans of paint cost 360 rubles, so the cost of one can can be found by dividing the total cost by the number of cans:

Cost of one can of paint = Total cost / Number of cans

In this case, the total cost is 360 rubles and the number of cans is 3. Therefore, the cost of one can of paint is:

Cost of one can of paint = 360 rubles / 3 cans = 120 rubles per can.

Next, we are told that a brush is five times cheaper than a can of paint. To find the cost of one brush, we can multiply the cost of one can of paint by the factor of five:

Cost of one brush = Cost of one can of paint * 5

Using the previously calculated cost of one can of paint (120 rubles), we can find the cost of one brush:

Cost of one brush = 120 rubles * 5 = 600 rubles per brush.

Finally, to determine how many brushes can be purchased with the same amount of money, we divide the total amount of money available by the cost of one brush:

Number of brushes = Total amount of money / Cost of one brush

Since the total amount of money is not specified in the question, we cannot provide an exact answer. However, if we assume that the total amount of money is 360 rubles (the same as the cost of three cans of paint), we can calculate the number of brushes:

Number of brushes = 360 rubles / 600 rubles per brush = 0.6 brushes.

Since we cannot purchase a fraction of a brush, we can conclude that with the same amount of money, it is not possible to buy any brushes.

Conclusion

Based on the given information, with the same amount of money that can buy three cans of paint for 360 rubles, it is not possible to buy any brushes.
