Answer 1

We meet again.  I see you are asking about another similar equation, and I will give you the same response I did last time.  You simply plug the values into the equation in solve, so it would look like this:
I=8,250*.039*7.
And you can do the rest.  I hope this was helpful, have a nice day! :)

Answer 2

ok so easy

I=PRT
t=time=7
r=rate3.9%=0.039
p=principal=8250

I=8250 times 0.039 times 7
I=8250 times 0.273
I=2252.25

$2252.25
