Answer 3

To find out the cost of the greeting cards and the envelopes, we can set up a system of equations based on the given information.

Let's assume the cost of each envelope and each greeting card is x.

According to the given information: - 35 envelopes and 25 greeting cards were purchased. - The total cost of the purchase was 5400 tenge.

Using this information, we can set up the following equations:

35x + 25x = 5400

Simplifying the equation, we get:

60x = 5400

Dividing both sides of the equation by 60, we find:

x = 5400 / 60 = 90

Therefore, the cost of each envelope and each greeting card is 90 tenge.

To find out the total cost of the greeting cards, we can multiply the cost of each greeting card by the number of greeting cards purchased:

Total cost of greeting cards = 25 * 90 = 2250 tenge.

So, the total cost of the greeting cards is 2250 tenge.

To find out the total cost of the envelopes, we can multiply the cost of each envelope by the number of envelopes purchased:

Total cost of envelopes = 35 * 90 = 3150 tenge.

So, the total cost of the envelopes is 3150 tenge.

In summary: - The cost of each envelope is 90 tenge. - The cost of each greeting card is also 90 tenge. - The total cost of the greeting cards is 2250 tenge. - The total cost of the envelopes is 3150 tenge.
