Question

I have no idea how to this. please explain step-by-step.. thnxx

Answer 1

Profit then 30M. Profit later, 210M.

Change in profit is obviously 180M, right?

OK, so that change is over how many years? 1992 to 1998 - 6 years.

Profit changed by 180,000,000 over 6 years, so on average it changed $180,000,000 / 6 per year.
