Answer 3

Calculating the Amount Spent on Gifts for Each Class

To calculate the amount spent on gifts for each class, we can use the information provided:

- The total amount spent on gifts for the 3 classes is 980 rubles. - The amount allocated for class 6A is the same as the amount allocated for class 6B. - The amount allocated for class 6V is 80 rubles more than the amount allocated for class 6B.

Let's denote: - The amount allocated for class 6A as A rubles. - The amount allocated for class 6B as B rubles. - The amount allocated for class 6V as C rubles.

We can set up the following equations based on the given information: 1. A + B + C = 980 (total amount spent on gifts for the 3 classes) 2. A = B 3. C = B + 80

We can solve these equations to find the amounts allocated for each class.

Solving the Equations

Substituting the value of A from equation 2 into equation 1: B + B + (B + 80) = 980 3B + 80 = 980 3B = 900 B = 300

So, the amount allocated for class 6B is 300 rubles.

Using the value of B, we can find the amounts allocated for classes 6A and 6V: A = B = 300 rubles C = B + 80 = 300 + 80 = 380 rubles

Therefore, the amounts spent on gifts for each class are: - 6A: 300 rubles - 6B: 300 rubles - 6V: 380 rubles
