Step-by-step explanation:
To determinate the price we will solve for the present value of the coupon payment and maturity at the market rate of %12
 
Coupon payment:
260,000,000 x 10% x 1/2 =13,000,000.000
time 20 years x 2 payment per year 40 
yield to maturity 12% / 2 = 6%
 
PV $195,601,859.3298 
 
 
 
 Maturity 260,000,000.00 
 time 40.00 
 rate 0.06
 
 
 PV 25,277,768.80 
 
PV c $195,601,859.3298 
PV m $25,277,768.8042 
Total $220,879,628.1340 
For the journal entries, we will multiply this current market price of the bonds by the market rate (YTM) the difference between this and the actual cash obligation generate by the bond is the amortization of the discount.
first interest payment 
$220,879,628.13 x 6% = 13,252,777.69
less actual cash outlay: 13,000,000
amortization 252,777.69
second interest payment
($220,879,628.13- $252,777.69) x 6% = 13,267,944.35
less actual cash outlay:  13,000,000.00
amortization 267,944.35
