please show me the formula and solution to this problem...

Answer 1

the equation for interest that isn't compouned continualy is P=P(not)*(1+(r/n))^(nt)
so
P=500*(1+(.05/2)^(2t)

you can do it out your self =p

Answer 2

Is it $50 or $500? are you depositing $50 or $500 every 6 months or withdrawing it?. What is due after 4.5 years?
Your question needs to be stated more clearly.
