Answer:
$4125.
Step-by-step explanation:
When solving for the principal we still need to use the formula .
Let's take all the variables that we do have available and list them out.
A = $4369.20
r = 3.3% or 0.033
n = 4 (Quarterly)
t = 21 months or 1.75 years
Now we can substitute the values and solve for the principal.
Now we need to divide both sides with 1.05919912849 to get the principal.
P = 4125.00339406 or $4125.
To check for our answer, we can simply substitute the values including the principal and excluding the total.
