Answer:
a. $18,100,000
b. $905,000
Step-by-step explanation:
The computations are shown below:
a. The number of dollars for the cash management system freed up is
= Per day in collections × reduced days + Per day in disbursements × increased days
= $4.90 million × 2.5 days + $3.90 million × 1.5 days
= $12,250,000 + $5,850,000
= $18,100,000
b. The interest income is
= Number of dollars for the cash management system freed up × interest rate per annum
= $18,100,000 × 0.05
= $905,000
