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