Hailey spent $12 to buy 2 fish. Her cousin spent double the amount on fish. Each fish cost the same amount. How many fish do Hailey and her cousin have altogether?

Okay Haley bought 2 fish for $12.

Her cousin spent double the amount, which is $24. Because each fish cost the same amount.

So if her cousin spent 24, then he bought 4 fish.

4 + 2 (Haley's fish) = 6

They have 6 fish all together.

Haley spent $ 12 ... her cousin spent double ... so her cuz spent $ 24

haley spent $ 12 for 2 fish ... 12/2 = 6 bucks per fish

so if the cuz spent $ 24 ... 24/6 = 4 ... cuz got 4 fish

haley's 2 fish + cuz's 4 fish = 6 fish in total
