Answer:
Excess cash available = 2000
Total funding required = 5000
Amount of interest paid = 50
Step-by-step explanation:
Determine the amount of interest paid in February: 
 
First calculate the shortage/excess of funds by deducting the cash payments from the sum of beginning cash balance and the cash receipts as below: 
 
Excess cash available = Beginning cash balance + Cash receipts – Cash payments 
Excess cash available = 10,000 + 40,000 – 48,000 
Excess cash available = 50,000 – 48,000 
Excess cash available = 2000 
 
Next, calculate the total funding required by deducting the excess cash available from the desired ending cash balance as below: 
 
Total funding required = Desired ending cash balance - Excess cash available 
Total funding required = 7000 – 2000 
Total funding required = 5000 
 
Finally, calculate the amount of interest paid in February by applying the rate of interest of 1 % on the total funding required as below: 
 
Amount of interest paid = Total funding require × Rate of interest 
Amount of interest paid = 5000 × 1% 
Amount of interest paid = 50
