The aquarium has 3 more yellow fish than green fish. 60 percent of the fish are yellow. How many green fish are in the aquarium? Show your work.

Step-by-step explanation:

Given

Solution

Then

Answer

We can write some variables to resemble the problem.

yellow fish = y

green fish = x

We can write a system of equations to resemble the problem.

y = x + 3

0.6(x + y) = y

Solve.

0.6(x + y) = y

0.6x + 0.6y = y

0.6x = 0.4y

0.6x = 0.4(x + 3)

0.6x = 0.4x + 1.2

0.2x = 1.2

x = 6

y = 6 + 3

y = 9

Therefore, there are 9 yellow fish and 6 green fish.
