Answer:
$594,338,200 was raised from the sale of the bonds.
Explanation:
The Price of the bond (PV) can be determined using a financial calculator as follows :
Pmt  = ($2,000 × 6.20 %) / 2 = $62
P/yr  = 2
n     = 15 × 2 = 30
YTM Â = 6.64 %
FV Â Â = Â $2,000
PV Â Â = ?
Therefore, PV = $1,917.22
Money raised = 310,000 bonds × $1,917.22
            = $594,338,200
