A mail-order firm processes 5,600 checks per month. Of these, 60 percent are for $46 and 40 percent are for $78. The $46 checks are delayed three days on average; the $78 checks are delayed four days on average. Assume 30 days in a month. a-1. What is the average daily collection float? (Do not round intermediate calculations.) Average daily collection float a-2. How do you interpret your answer? (Do not round intermediate calculations.) On average, there is that is and to the firm b-1. What is the weighted average delay? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g. 32.16.) Weighted average delay days b-2. Calculate the average daily float. (Do not round Intermediate calculations.) Average daily float How much should the firm be willing to pay to eliminate the float? (Do not round intermediate calculations.) Maximum payment d. If the interest rate is 7 percent per year, calculate the daily cost of the float (Use 365 days a year. Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Daily cost of the float e. How much should the firm be willing to pay to reduce the weighted average float to 1.5 days? (Do not round intermediate calculations.) Maximum payment
