Question

The trunk of a tree is 50 cm thick. Each year it gets thicker by 1 cm . How thick will the tree trunk be in 50 years?

Answer 1

It’s already 50cm and it grows 1 cm each year, so 1cm times 50 years =50cm plus the other 50=100cm

Answer 2

100cm

Explanation:

It starts at 50cm.

Each year you're adding 1cm.

1cm*50 years = 50cm

50+50=100
