When inflation causes the price of an item to increase the new cost C and the original cost c are related by the formula C=c(1+r)^n, where r is the rate of inflation per year as a decimal and n is the number of years. What would be the price of a $4.99 item after six months of 5% inflation?

C = 4.99(1+.05)^1/2
