Answer:

$63,900.00

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 21%/100 = 0.21 per year.

Solving our equation:

A = 45000(1 + (0.21 × 2)) = 63900

A = $63,900.00

The total amount accrued, principal plus interest, from simple interest on a principal of $45,000.00 at a rate of 21% per year for 2 years is $63,900.00.
