Let C be the total cost in n years, then
\n" ); document.write( "C = 20(1 + 0.05)^n
\n" ); document.write( "Note that this equation comes from the following formula
\n" ); document.write( "A = P(1 + r/n)^nt, A is accumulated amount, P is principle, r is rate, n is number of compounds per year, t is number of years\r
