Answer:

12% per year

Explanation:

first we must determine the inflation rate:

  • inflation rate year 1 = (110 - 100) / 100 = 10 / 100 = 0.1 or 10%
  • inflation rate year 2 = (121 - 110) / 110 = 11 / 110 = 0.1 or 10%

nominal interest rate = real interest rate + inflation rate = 2% + 10% = 12%

That way, Frank should collect = $1,000 x 1.12² = $1,254.40 in two years if he charges compound interest.
