Calculation Steps: First, convert R as a percent to r as a decimal r = R/100 r = 2/100 r = 0.02 per year,

Then, solve the equation for P P = A / ert P = 100.00 / e(0.02*10) P = $81.87

Summary: The principal investment required to get a total amount of $100.00 from compound interest at a rate of 2% per year compounded continuously over 10 years is $81.87.
