Help with calculations I figured it out on my own but not sure if correct? Please help!!!

Question

2018-2019 semester

Apartment
2 bedroom
2 bathroom
700 sq. Ft
Green fee $10.00
Utilities $ 60.00
2 people
Rent $975

$975÷2 =$487.5
$487.5-7months=$480.5

Financial aid: $21,720.00
Fees : $4,902.00
Fees : $300

So, I took $21,720.00-$4802.00+$300=$17,118
Then took $17,118-$480.5=$16,637.5

So I have $16,637.5 left?

Answer 1

This line left me confused.
$487.5-7months=$480.5

If your rent is 487.50/month for 7 months, that's $3412.50

If your fees are
Fees : $4,902.00
Fees : $300
then you should subtract both, right?

So, I get

21,720.00-(4902+300) - 3412.50
21,720-4902-300-3412.50 = 13,105.50

Answer 2

I dont follow
a) isn't rent costs per month?
b) isn't FA per semester?
It looks to me as you mixed those.

Answer 3

What about the $10 "green fees" and $60 utilities per month?
So wouldn't the monthly cost be (975+10+60)/2 or $522.5 ?
