Answer: $463,067.50
Explanation:
Calculation of single bill payment i.e. Future value
[tex]Future\ value=Present\ value\times(1+r)^{n}-Payment\times\frac{(1+r)^{n}-1 }{r}[/tex]
[tex]Future\ value=250,000\times(1+\frac{5.45}{1200} )^{360}-900\times\frac{(1+\frac{5.45}{1200} )^{360}-1 }{\frac{5.45}{1,200} }[/tex]
              = $250,000 × 5.110505847 - $900 × 905.06551
              = $1,277,626.46 - $814,558.96
              = $463,067.50
Therefore, the single balloon payment will be $463,067.50
