Answer:
Mary removed the dollar sign from (X.)
We know this because $4.00x$5.00=$20.00 so that’s correct and we know that $12.50x $4.00=$50.00. So, our only error here is that there is no dollar sign in our (X) numbers. So that is Mary’s mistake. We can correct it by simply adding a dollar sign to 20 to make $20.00 and adding another dollar sign to 50 to make $50.00

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.
