Answer:
$1,650
Step-by-step explanation:
The computation of the total amount paid to bondholders is shown below: 
= Issued amount × rate of interest × number of months ÷ (total number of months in a year) 
= $33,000 × 10% × (6 months ÷ 12 months) 
= $1,650 
The six months are calculated from June 30 to December 31. And, we simply use the simple interest formula so that the correct amount can come.
