A.) A = P (1 + r)^t
P = 500 ; r = 3% ; t = 2
A = 500 (1 + 0.03)²
A = 500 (1.03)²
A = 500 * 1.0609 numerical expression
A = 530.45
A numerical expression is an expression that involves purely numbers and one or more operational symbols.
B) compound interest for 2 years.
530.45 - 500 = 30.45 is the compound interest for 2 years.
