Question

In a video game,a guppy that escapes a net turns into three goldfish.Each goldfish can turn into two betta fish.Each betta fish can turn into two angelfish.Write and evaluate an expression for the number if angelfish that can be formed from one guppy.

Answer 1

If g=guppy, go=goldfish, b=bettafish and a=angelfish we can set up expressions for each set of fish.
1g=3go
1go=2b
1b=2a

By working backwards and substituting we can finally work out 1 guppy to be equal to 12 angelfish.
