A mail-order firm processes 5,800 checks per month. Of these, 60 percent are for $49 and 40 percent are for $84. The $49 checks are delayed two days on average; the $84 checks are delayed three days on average. Assume 30 days in a month. a-1. What is the average dally collection float? (Do not round Intermediate calculations.) a-2. How do you interpret your answer? (Do not round intermediate calculations.) b-1. What is the weighted average delay? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g.. 3216 .) b-2. Calculate the average daily float. (Do not round intermedate calculations.) c. How much should the firm be willing to pay to eliminate the float? (Do not round intermedlate calculations.) d. If the Interest rate is 7 percent per year, calculate the dally cost of the float. (Use 365 days a year. Do not round intermedlate calculations and round your answer to 2 decimal places, e.9. 32.16.) e. How much should the firm be willing to pay to reduce the weighted average float to 1.5 days? (Do not round intermedlate calculations.)
