Question

Mr. Sim invest $9000 at 1% per annum compound interest compounded daily. What is his amount at the end of the third day?

Answer 1

Answer:

The amount at the end of the third day is $9,000.74

Step-by-step explanation:

To calculate his amount, we shall be using the compound interest formula;

Mathematically;

A = I( 1 + r)^nt

where A is the amount which we want to calculate

I is the initial amount deposited = $9,000

r is the interest rate = 1% = 1/100 = 0.01

the daily interest will be 0.01/365 = 0.00002739726

nt is the number of times we shall be compounding = 3 times

Substituting these values;

A = 9,000(1 + 0.00002739726)^3

A = 9,000(1.00002739726)^3

A = 9,000.73974628665

which is approximately; 9,000.74
