Im a bit stuck on a question I have to do.
I need to find the annual average decrease between 1982-7.45 and 2003-6.15. Is it 6.15+7.45/12=1.13 per year Or do I just divide by 2 or the number of years inbetween? Also if I want to say 1.13 million is it written as 1.135 (to the powers of 5) and does anyone know how to get the little 5 above the bigger numbers?
Any advice would be absolutely fantastic.
