A=P(1+r/n)^nt
\n" ); document.write( "The problem is Kevin deposits $1000 at 9% annual interest, compounded quarterly. How long will it take for the account to earn $1000 interest?
\n" ); document.write( "------------------------
\n" ); document.write( "The value of the account will be $2000
\n" ); document.write( "--------------------------------------------
\n" ); document.write( "2000 = 1000(1+(.09/4)^(4t)
\n" ); document.write( "---------------------------------
\n" ); document.write( "2 = 1.0225^(4t)
\n" ); document.write( "4t = log2/log1.0225
\n" ); document.write( "4t = 31.15
\n" ); document.write( "t = 7.79 years
\n" ); document.write( "=====================
