Tony has two fish. Every year, his parents buy him two more, but one of them dies. How many fish will he have in five years?
assistant
How many more fish does Tony have each year? ** Each year Tony has one more fish than before because 2 - 1 = <<2-1=1>>1
How many more fish will Tony have in five years? ** In five years, he will have 5 more fish because 5 x 1 = <<5*1=5>>5
How many fish will Tony have in five years? ** In five years he will have 7 fish because 2 + 5 = <<2+5=7>>7
