calculate the simple interest of $20,000 a loan at the interest rate of 8% after five years

8,000
800,000
80,000
1,600

To calculate the simple interest, you can use the formula:

Simple Interest = Principal x Rate x Time

Given:
Principal (P) = $20,000
Rate (R) = 8% = 0.08
Time (T) = 5 years

Using the formula:

Simple Interest = $20,000 x 0.08 x 5
Simple Interest = $8,000

Therefore, the simple interest on the loan after five years is $8,000.
