Tom and Jim have a total of 57 fish. Tom has 16 goldfish and 5 betta fish.
If Jim has 8 more goldfish than Tom, how many betta fish does
Jim have?
betta fish

12

Step-by-step explanation:

Tom's fish    

goldfish=16

betta fish=5

total tom's fish=21

Jim's fish

goldfish=16+8=24

 21+24=45

57-45=12

so jim has 12 betta fishs

total = 57

all together Tom has 21 fish

if Jim has 8 more that makes it 24 gold fish for himself

21+24=45 / blank betta fish for Jim

57-45= 12 betta fish
