Problem Analysis

To solve this problem, we need to determine the cost of each type of fabric (red, blue, and green) based on the given information. We know that the total cost of the purchase was 1000 rubles, and the cost of the red fabric was 76 rubles more than the combined cost of the blue and green fabrics. Additionally, the cost of the red fabric was 5 times the cost of the blue and green fabrics combined.

Solution

Let's assume the cost of the blue and green fabrics combined is x rubles. Therefore, the cost of the red fabric would be 5x + 76 rubles. We can set up the following equation to represent the total cost of the purchase:

x + x + 5x + 76 = 1000

Simplifying the equation:

7x + 76 = 1000 7x = 924 x = 132

Now that we have the value of x, we can calculate the cost of each fabric:

- The cost of the blue and green fabrics combined (x) is 132 rubles. - The cost of the red fabric is 5x + 76 = 5 * 132 + 76 = 660 + 76 = 736 rubles.

Therefore, the cost of each fabric is as follows:

- Blue and green fabric: 132 rubles each. - Red fabric: 736 rubles.

Answer

Based on the given information, the cost of each fabric is as follows: - Blue and green fabric: 132 rubles each. - Red fabric: 736 rubles.
