If $125 is invested at an interest rate of 18% per year and is compounded continuously, how much will the investment be worth in 2 years? Use the continuous compound interest formula A = Pert.

Given:

Principal Amount ( P ) = $125

Interes Rate ( r ) = 18% or 0.18 ( divide by 100)

Term ( t ) = 2

Compounded continuously ( n ) = 1

Formula for Compound Interest:

A = P ( 1 + r/n)^nt

A = Future value

A = Pert is the formula used for simple interest.
Solution:

Substitute the given values of P, r, n and t to the formula for the compound interest.

A = $125 ( 1 + 0.18/1)^(2)(1)

A = $125 (1.18)^(2)

A = $125 (1.3924)

A = 174.05
Final answer:
A = 174.05
