Answer:
B. $300
Explanation:
The interest revenue is computed below:
= Principal × rate of interest × number of months ÷ (total number of months in a year)
= $20,000 × 6% × (3 months ÷ 12 months)
= $300
The 6 months is calculated from October 1 to December 31
Simply we use the simple interest formula by considering the principal amount, rate of interest and time period so that the correct revenue can be computed
