In still trying to figure out the equation for S=C(1+r/100)^5
to help me to find the inflated cost S, in 5 years, for sunglasses they cost 3.72103 in Afghanistan currency which will go into the C spot of the equation. which these glasses will cost $169.40 in U.S. Dollars. So how do I calulate to get the inflated rate for r%. in 5 years. also could it be that $169.40 is the inflated cost and I have to figure out the r% of $169.40 just confuse.
