Simple interest $2,000 at 10% Year 1: $2,000 *.10 = $200 $2,000 + $200 = $2,200 Year 2: $2,000 *.10 = $200 $2,200 + $200 = $2,400 What would the value be at the end of year 3? Compound interest $2,000 at 10% Year 1: $2,000 *.10 = $200 $2,000 + $200 = $2,200 Year 2: $2,200 *.10 = $220 $2,200 + $220 = $2,420 What would the value be at the end of year 3?
