Question

The combined average weight of an okapi and a llama is 450 kilograms. The average weight of 3 llamas is 190 kilograms more than the average weight of one okapi.

On average, how much does an okapi weigh, and how much does a llama weigh?

[AI-generated answer — Bot GPT 3.5]

Let's denote the weight of an okapi as O kilograms and the weight of a llama as L kilograms.

From the information given, we can set up the following equations:
1. O + L = 450 (combined average weight of an okapi and a llama)
2. 3L = O + 190 (average weight of 3 llamas is 190 kilograms more than the average weight of one okapi)

We can solve this system of equations by substituting equation 2 into equation 1:
O + 3L = 450
O + (O + 190) = 450
2O = 260
O = 130

Substitute the value of O back into equation 2 to solve for L:
3L = 130 + 190
3L = 320
L = 106.67

On average, an okapi weighs 130 kilograms and a llama weighs approximately 106.67 kilograms.
