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 righthand side.
b) Find A if $8300 is invested for 3 years at a simple interest of 15%

Math 
Sarah,
a) A=P(1+rt)
b) A=8300*(1+3(.15))

JASMIN,
Just a question? Can't two people have the same question? There is hundreds of people on here... Just asking...

Math 
Reiny,
yes, of course that can happen.
But instead of typing the solution all over again, doesn't it make sense to direct a student to the other post, when that post contains the solution?
