Problem Analysis

To solve this problem, we need to determine the number of greeting cards sent by Katya. We are given that Tanya sent 7 greeting cards, and Katya sent 5 more than Tanya.

Solution

To find the number of greeting cards sent by Katya, we can add 5 to the number of greeting cards sent by Tanya.

Let's denote the number of greeting cards sent by Tanya as T and the number of greeting cards sent by Katya as K.

We are given that T = 7.

To find K, we can use the equation K = T + 5.

Substituting the value of T into the equation, we get K = 7 + 5.

Therefore, K = 12.

So, Katya sent 12 greeting cards.

Answer

Katya sent 12 greeting cards.
