Answer:
$307,500
Step-by-step explanation:
The computation of the amount needed to pay back the note payable plus any accrued interest is shown below
= Note payable amount + note payable amount × rate of interest × number of months ÷ total number of months in a year
= $300,000 + $300,000 × 5% × 6 months ÷ 12 months
= $300,000 + $7,500
= $307,500
Therefore, the amount needed to pay back is $307,500
