Answer:
b. $2,000
Step-by-step explanation:
The computation of the interest amount is shown below:
= Sale value of goods × rate of interest × (number of months ÷ total number of months in a year)
= $40,000 × 10% × (6 months ÷ 12 months)
= $2,000
The 6 months is calculated from June 30 to December 31.
So, the b option is correct and rest options are wrong.
