Answer:

$18206.5

Step-by-step explanation:

Considering,  r = interest rate

    n = number of intervals

    t = duration of the payment

    A = monthly installment  

   PV = Present Value

   FV = Final Value

Using the formula

FV=PV (1+ r/n[tex])^{nt-1[/tex] + a((1+ r/n[tex])^{nt[/tex]-1/[tex]\frac{r}{n}[/tex])

FV=6000[tex](1+ \frac{0.03}{12} )^{(12)(4)-1} +225\frac{(1+0.03/12)^{(12)(4)}-1 )}{0.03/12}[/tex]

FV= 6747 + 11459.5

FV=18206.5

Her balance in 4 years is $18206.5
