if sandra invested 30,000 at 8% compounded annually. what will be her total balance at the end of 2 years?
\n" ); document.write( "--------
\n" ); document.write( "A(t) = P(1+(r/n))^(nt)
\n" ); document.write( "A(2) = 30,000(1+(0.08/1))^(1*2)
\n" ); document.write( "A(2) = 30,000(1.08)^2
\n" ); document.write( "A(2) = $34,992
\n" ); document.write( "===================================\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "#2 is 20,000 for 2 years at 6% compounded annually. how much interest is earned for the investment?
\n" ); document.write( "---
\n" ); document.write( "Interest = A(t) - P
\n" ); document.write( "= 20000(1.06)^2 - 20000
\n" ); document.write( "= 20000[1.06^2-1]
\n" ); document.write( "= 20000(0.1236)
\n" ); document.write( "----
\n" ); document.write( "= $2472
