Answer 3

Solution:

To solve this problem, we can set up an equation based on the given information and then solve for the number of cards Olya made.

Let's denote the number of cards Olya made as O and the number of cards Polya made as P. We know that Olya made 4 times as many cards as Polya, and the total number of cards was 30.

We can express this information in the form of an equation: O = 4P (Olya made 4 times as many cards as Polya) O + P = 30 (The total number of cards was 30)

Now, we can solve these equations to find the value of O (the number of cards Olya made).

First, we can substitute the value of O from the first equation into the second equation: 4P + P = 30 5P = 30 P = 6

Now that we have the value of P, we can find the value of O using the first equation: O = 4 * 6 O = 24

Answer:

So, Olya made 24 cards.
