Answer:
$450
Explanation:
To calculate simple interest, we apply the formula
I= P x r x t
Where I = interest
P= principal
r= interest rate
t= time in years
In this case, p=$8,000, r= 7.50% or 0.075, t= 9 months or 9/12 years which is 0.75 years
I =$8000 x 0.075 x 0.75
I= $600 x 0.75
I=$450
Interest is $450
