Question

The number of yellow fish at the aquarium is 5 fewer than 3 times the number of blue fish. The table shows how the number of yellow fish, y, depends on the number of blue fish, b. Choose the equation which represents the rule.

Answer 1

y = 3b-5

Explanation:

The number of yellow fish is 5 fewer than 3 times the number of blue fish. Using b to represent the number of blue fish, 3 times this is 3b; 5 fewer than this is 3b-5. This gives us the equation

y = 3b-5

Answer 2

If you are on USATestPrep (which you most likely are) the correct answer is C.

Explanation:

C) y = 3b − 5

It is “5 fewer than 3 times”
