Question

I need help doing this ?

Answer 1

It would be 21.6

Explanation:

First 2% of 16000 is 320.

Now we take our wanted value of 22900 and subtract 16000 from it to get 6900.

We take our difference of 6900 and divide this by 320 and get 21.5625

That rounded to the nearest tenth is 21.6

Answer 2

It should be approximately 21.6 years.
