The aquarium has 10 more red fish than blue fish. 60 percent of the fish are red. How many blue fish are in the aquarium?
guajiro [1.7K]

Answer:

20 blue fish

Step-by-step explanation:

Number of blue fish = x

Number of red fish = x+10

Red fish = 60% of total = 0.6

Total fish = x+x+10 = 2x+10

0.6 = (x+10)/(2x+10)

Solve for x:

1.2x+6 = x+10

0.2x = 4

x = 20

Hope this helps!
