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.
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+0.45)
A = 8300(1.45) = $12035.00
