How many goldfish did Calvin buy?

(2 bowls x 6 goldfish) + 3 goldfish in a bag = 15 goldfish

Calculate the number of fish in 1 bowl and in the bag together.

(1 bowls x 6 goldfish) + 3 goldfish in a bag = 9 goldfish

Divide that number by the number of bowls.

9 goldfish / 2 bowls = 4.5 goldfish

Calculate how many goldfish are in 2 fish bowls.

2 bowls x 6 goldfish = 12 goldfish

Add that number to the number of fish in the bag.

12 goldfish + 3 goldfish = 15 goldfish

Calculate how many more goldfish are in a bowl than the bag.

6 goldfish - 3 goldfish = 3 goldfish more in a bowl than in a bag

Multiply that number by the number of bowls.

3 goldfish x 2 = 6 goldfish

Calculate how many fish bowls there are.

2 fish bowls

Add that number to the number of fish in the bag.

2 + 3 = 5
