Answer:

0.0625/year or 6.25%/year

Step-by-step explanation:

Simple interest formula:

  • I = Prt
  • where I = interest (final) amount, P = principal (initial) amount, r = interest rate, t = time (years)

We are given these values:

  • I = $500
  • P = $4000
  • t = 2 years

We want to find r, the simple interest rate.

Substitute these known values into the formula.

  • I = Prt
  • 500 = (4000) × r × (2)  
  • 500 = 8000r
  • 0.0625 = r

The simple interest rate is 0.0625, aka 6.25% per year.
