I’m assuming there is a picture you are missing.
D) 96 (the circle graph counts it out for you) hope this helps!!
Double
from initial amont of P to final amount of 2P
so
2P=P(1.071)^time
divide both sides by P
2=1.071^time
take the ln of both sides
ln2=timeln1.071
divide both sides by ln 1.071
(ln2)/(ln1.071)=time needed
using calculator
10.1052=time needed
about 10.1 hours
Let's calculate how much do you spent paying monthly $165:
24*165=3960 ($)
If you pay cash you will spent $3438
The difference between those two is how much you save paying cash:
3960 - 3438 = 522 ($)
The answer is C.
