Answer 2

To solve this problem, let's break it down step by step.

1. We know that if Petya bought shorts with a t-shirt, the cost would be twice as much. 2. If Petya bought shorts with boots, the cost would be six times as much. 3. If Petya bought shorts with shin guards, the cost would be three times as much.

Now, let's calculate the cost of each item individually and then add them up.

Let's assume the cost of shorts is x.

1. If Petya bought shorts with a t-shirt, the cost would be twice as much. So the cost of the t-shirt would also be x. - The total cost of shorts and a t-shirt would be 2x.

2. If Petya bought shorts with boots, the cost would be six times as much. So the cost of the boots would be 6x. - The total cost of shorts and boots would be x + 6x = 7x.

3. If Petya bought shorts with shin guards, the cost would be three times as much. So the cost of the shin guards would be 3x. - The total cost of shorts and shin guards would be x + 3x = 4x.

Now, let's calculate the total cost if Petya bought shorts, a t-shirt, boots, and shin guards.

- The total cost would be the sum of the individual costs: 2x + 7x + 4x = 13x.

Therefore, if Petya bought shorts, a t-shirt, boots, and shin guards, the cost of the purchase would be 13 times the cost of the shorts alone.

I hope this helps! Let me know if you have any further questions.
