Answer:
B) $250 gain.
Step-by-step explanation:
The cost per bond is $1,010.
The amortization amount each year is 10/20 years = $0.50 per year. $0.50 per year × 10 years = $5 per bond.
After 10 years, the adjusted cost basis is $1,005 per bond.
She sells the bonds for $1,030 per bond. $1,030 − $1,005 = $25 per bond
25 × 10 = $250 gain.
