Answer:
$26,700 excess
Explanation:
The amount of deficiency or excess can be determined only when the ending cash balance is known. The ending cash balance is the addition of the net movement in cash to the opening cash balance.
The net movement is the difference between the total receipts and the total payments or disbursement.
Total receipts for January
= $1,061,200 
Total payments
= $984,500 
Net movement = $1,061,200   - $984,500  
= $76,700
Ending balance = $290,000 + $76,700
= $366,700
If the minimum cash requirement is $340,000
The amount of the (deficiency)/excess cash (after considering the minimum cash balance required) for January
= $366,700  - $340,000
= $26,700
 
        
             
        
        
        
Answer:
c. $326,948
Explanation:
we must determine the market price of the bonds:
market price = PV of face value + PV of coupons
- PV of face value = $300,000 / (1 + 2%)¹⁰ = $246,104.49
- PV of coupons = $9,000 (coupons) x 8.9826 (PV annuity factor 2%, 10 periods) =   $80,843.40
total market price = $326,947.89 ≈ $326,948
since the market rate is lower than the coupon rate, the bonds should be sold at a premium.
