Answer 2

Problem Analysis

We are given that 15 tables and 20 stools were purchased for a total price of 235 rubles. The price of the stools is 5 times less than the price of the tables. We need to find the cost of the purchase and determine how much more was paid for the tables compared to the stools.

Solution

Let's assume the price of one table is x rubles. According to the given information, the price of one stool is x/5 rubles.

The total cost of the tables can be calculated as 15 * x rubles, and the total cost of the stools can be calculated as 20 * (x/5) rubles.

We are given that the total cost of the purchase is 235 rubles. Therefore, we can set up the following equation:

15 * x + 20 * (x/5) = 235

Simplifying the equation:

15x + 4x = 235

19x = 235

Solving for x:

x = 235 / 19

x ≈ 12.37

The cost of one table is approximately 12.37 rubles, and the cost of one stool is approximately 2.47 rubles.

To find the total cost of the purchase, we can substitute the value of x back into the equation:

Total cost = 15 * 12.37 + 20 * (12.37/5)

Total cost ≈ 185.55 + 49.48

Total cost ≈ 235.03

Therefore, the total cost of the purchase is approximately 235.03 rubles.

To find how much more was paid for the tables compared to the stools, we can subtract the total cost of the stools from the total cost of the purchase:

Difference = Total cost of tables - Total cost of stools

Difference = 185.55 - 49.48

Difference ≈ 136.07

Therefore
