Answer 2

Problem Analysis

We are given the following information: - 4 cups were purchased at a price of 54 rubles per cup. - 2 glasses were purchased.

We need to find the total cost of 4 cups and 2 glasses, given that the cups are 2 times cheaper.

Solution

Let's calculate the cost of the cups and the glasses separately, and then find the total cost.

1. Cost of 4 cups: - Each cup costs 54 rubles. - Since the cups are 2 times cheaper, the actual cost of each cup is 54 / 2 = 27 rubles. - Therefore, the total cost of 4 cups is 4 * 27 = 108 rubles.

2. Cost of 2 glasses: - The cost of the glasses is not provided in the question. - We cannot determine the cost of the glasses without additional information.

Answer

The total cost of 4 cups and 2 glasses cannot be determined without knowing the cost of the glasses.
