$f(x)=3x-7\\\\g(x)=x^2-4\\\\(f-g)(x)=f(x)-g(x)\\\\Therefore\\\\(f-g)(-5)=f(-5)-g(-5)\\\\Put\ the\ value\ of\ x=-5\ to\ the\ equation\ of\ the\ function\ f\\and\ to\ the\ equation\ of\ the\ function\ g:\\\\f(-5)=3(-5)-7=-15-7=-22\\\\g(-5)=(-5)^2-4=25-4=21\\\\(f-g)(-5)=-22-21=-43\to\boxed{C.}$

Mathematics

the monthly payment is $636.02

Step-by-step explanation:

The computation of the monthly amount deposited i.e. PMT is given below:

GIven that

NPER = 15 × 12 months = 180

RATE = 5% ÷ 12 = 0.4167%

PV = $0

FV = $170,000

based on the above information

The formula is shown below:

= PMT(RATE;NPER;PV;FV;TYPE)

AFter applying the above formula, the monthly payment is $636.02
