Question

Of the 25 fish that Karl caught

from the lake, 7 were trout. The
estimated population of the lake is
6,500 fish. About how many trout
would
you expect to be in the lake?

Answer 1

1,820 trout

Explanation:

Set up a proportion where x is the number of trout in the lake:

`(7)/(25)` =
`(x)/(6,500)`

Cross multiply and solve for x:

25x = 45,500

x = 1820

So, you could expect 1,820 trout to be in the lake.
