Answer: B.
Step-by-step explanation: B is the only option that provides the division symbol.
Substitute x for 7.
f(x)=22x+12
f(7)=22(7)+12
Multiply first, then complete addition.
f(7)=154+12
f(7)=166
Solution:
As per the problem
Maxine took out a loan for $3200 at 8% interest, compounded annually.
she makes yearly payments of $250.
she will be able to Payoff her loan iff yearly payments made is greater than yearly interest.
Interest payable in first year 
Interest payable in first year
This payable interest will goes on increasing year on year.
Hence Maxine will never payoff the loan.
The momentum formula is
p = m*v
where,
p = momentum (not sure why p is chosen but many physics books tend to pick this letter)
m = mass in kilograms
v = velocity in meters per second
So let's calculate the momentum for the 4500 kg vehicle
p = m*v
p = 4500*85
p = 382500 kg m/s
And let's do the same for the 3700 kg vehicle
p = m*v
p = 3700*85
p = 314500 kg m/s
The answer is D. No relationship but there’s no question for it so it maybe wrong
