question 8, you had to minus 180 from the 720 that gives you 540 as your Principal, then use the Simple Interest formula  I = Prt/100 find out the interest, then add it to the Principal of $540 and divide it by 24.

Question 9, type it in TVM solver lol

N= 240
I = 7
Pv = 250000
FV= 0
PMT = ?
P/Y = 12
C/Y = 12

find out the monthly payment PMT then times it by 240 and minus the principal.
