This problem can be solved using the formula for the annuity.
Principal amount = price of the sofa(1 + sales tax)
where
price of the sofa= $670
sales tax =7.94%
Principal amount = $723.2
solve for the amortization using the formula:
Amortization = Principal amount[(i(1+i)^n]/[(1+i)^n-1]
where
i= 11.05%/12=.92%
n= 3years x 4 payments/year=36
Principal amount = $723.20
Amortization = $23.68
Get the sum of annuity
Sum of annuity=Amortization[(1+i)^n-1]/i
Sum of annuity= $852.84
The answer is letter d. Douglas paid a total of $852.84 for the sofa.
