Answer:

$9891.23

Step-by-step explanation:

The formula for future value of annuity due is:

$FV=P[\frac{(1+r)^{n}-1}{r}]*(1+r)$

Where,

FV is the future value of the annuity (what we need to find)
P is the periodic payment (here it is $400)
r is the interest rate per period (here 13% yearly interest is actually $\frac{13}{4}=3.25$ percent per period(quarter))
n is the number of periods (here the annuity is for $4\frac{1}{2}$ years, which is $4\frac{1}{2}*4=18$ periods, since quarterly and there are 4 quarters in 1 year)
