<PRE><B>Question 76322</B>
The amount of an investment of P dollars for t years at simple interest rate r is given by A = P + Prt. 
a) Rewrite this formula by factoring out the greatest common factor on the right hand side.
A = P(1+rt)
-------- 
b) Find A if $8300 is invested for 3 years at a simple interest rate of 15%.
A = 8300(1+(0.15)*3)
A = 8300(1.45)
A = $12,035
