Problem Analysis

We are given three teenagers who received 2500 rubles for planting trees. The first teenager planted 75 trees, the second planted 45 more trees than the first, and the third planted 65 fewer trees than the second. We need to determine how much money each teenager received.

Solution

Let's solve this problem step by step:

1. Let's assume that the first teenager received x rubles for planting trees. 2. The second teenager planted 45 more trees than the first, so the second teenager planted 75 + 45 = 120 trees. 3. The third teenager planted 65 fewer trees than the second, so the third teenager planted 120 - 65 = 55 trees. 4. Since the first teenager planted 75 trees, they received x rubles. 5. The second teenager planted 120 trees, so they received x + 45 rubles. 6. The third teenager planted 55 trees, so they received x - 65 rubles. 7. The sum of the amounts received by the three teenagers is 2500 rubles, so we can write the equation: x + (x + 45) + (x - 65) = 2500. 8. Simplifying the equation, we get: 3x - 20 = 2500. 9. Solving for x, we find: 3x = 2520 and x = 840.

Therefore, the first teenager received 840 rubles, the second teenager received 840 + 45 = 885 rubles, and the third teenager received 840 - 65 = 775 rubles.

Answer

The first teenager received 840 rubles, the second teenager received 885 rubles, and the third teenager received 775 rubles.
