Problem Analysis

We are given the following information: - The brush originally cost 240 rubles. - It is being sold with a 25% discount. - The buyer purchased two brushes and paid 500 rubles.

We need to calculate the amount of change the buyer should receive.

Solution

To find the original price of the brush before the discount, we can use the formula:

Original Price = Discounted Price / (1 - Discount Percentage)

Let's calculate the original price of the brush:

Discounted Price = 240 rubles - (240 rubles * 25%) = 240 rubles - (240 rubles * 0.25) = 240 rubles - 60 rubles = 180 rubles

Original Price = 180 rubles / (1 - 0.25) = 180 rubles / 0.75 = 240 rubles

So, the original price of the brush is 240 rubles.

Since the buyer purchased two brushes, the total cost of the brushes is 2 * 240 rubles = 480 rubles.

The buyer paid 500 rubles, so the change they should receive is:

Change = Amount Paid - Total Cost = 500 rubles - 480 rubles = 20 rubles

Therefore, the buyer should receive 20 rubles in change.

Answer

The buyer should receive 20 rubles in change.
