Answer 2

Calculating the Cost of the Jacket

To calculate the cost of the jacket, we can use the given information about its price in relation to the prices of hats.

Let's denote: - Cost of the jacket as J - Cost of one hat as H

Given: - The jacket is 700 rubles cheaper than 5 hats - The jacket is 200 rubles more expensive than 2 hats

We can express these relationships as equations: 1. J = 5H - 700 2. J = 2H + 200

To find the cost of the jacket, we can solve these equations simultaneously.

First, we'll solve equation 2 for H: J - 200 = 2H H = (J - 200) / 2

Now, we'll substitute the value of H from equation 2 into equation 1: J = 5((J - 200) / 2) - 700 J = (5J - 1000) / 2 - 700 2J = 5J - 1000 - 1400 2J = 5J - 2400 2J - 5J = -2400 -3J = -2400 J = -2400 / -3 J = 800

So, the cost of the jacket is 800 rubles.
