Amount of an investment. 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.
b) Find A if $8300 is invested for 3 years at a simple
interest rate of 15%.

...
A=P+Prt
A=P(1+rt)
A=8300(1+0.15*3)
A=8300(1.45)
A=$ 12035
