<PRE><B>Question 50622</B>
Simplify the expression completly: (12m + 4n)+(3m+7n)?
=15m+11n
--------------------

If you had 450 dollars in your bank account that pays interest at 3% annually how much will you have after 2 years?

Simple interest formula Amount = Principle + Principle*rate*time= P(1+rt)
Your problem: Amount = 450(1+(0.03)2)= 450(1+0.06)=$477.00
If the bank pays compound interest the formula is A=P(1+r)^2
Your problem: Amount = 450(1+0.03)^2= $477.41
