Question

Answers matching "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?"

Answer 1

Let us say that:

x = weight of llamas

y = weight of okapi

 

From the problem, we can create the equations:

x + y = 450           --> 1

3 x = y + 190        --> 2

 

Rewriting equation 1:

x = 450 – y

 

From equation 2:

3 (450 – y) = y + 190

1350 – 3 y = y + 190

4 y = 1160

y = 290

 

From equation 1:

x = 450 – 290

x = 160

 

Therefore a llama weighs 160 kilograms while okapi weigh 290 kilograms on average.
