Answer:

The interest rate was 15%

Step-by-step explanation:

The simple interest formula is the easiest and most straightforward to use since it doesn't involve using logs or natual logs or Euler's number.  It is

I = Prt

Filling in using our info gives us 300 = 1000(r)(2)

and 300 = 2000r

Divide both sides by 2000 and you get r = .15.  Multiply by 100 to get the percentage.
