Answer:
$150
Explanation:
The simple interest can be calculated using the following equation
I = Prt
Where P is the principal, r is the rate as a decimal and t is the number of years.
So, replacing P = $4000, r = 5% = 0.05 and t = 3/4 years, we get:
I = ($4000)(0.05)(3/4)
I = $150
Therefore, the simple interest is $150
