Simplify the expression completly: (12m + 4n)+(3m+7n)?
\n" ); document.write( "=15m+11n
\n" ); document.write( "--------------------\r
\n" ); document.write( "\n" ); document.write( "If you had 450 dollars in your bank account that pays interest at 3% annually how much will you have after 2 years?\r
\n" ); document.write( "\n" ); document.write( "Simple interest formula Amount = Principle + Principle*rate*time= P(1+rt)
\n" ); document.write( "Your problem: Amount = 450(1+(0.03)2)= 450(1+0.06)=$477.00
\n" ); document.write( "If the bank pays compound interest the formula is A=P(1+r)^2
\n" ); document.write( "Your problem: Amount = 450(1+0.03)^2= $477.41
\n" ); document.write( "-------------\r
