The officers of a high school senior class are planning to rent buses and vans for a class trip. Each bus can transport 80 students, requires 5 chaperones, and costs $1,000 to rent. Each van can transport 10 students, requires 1 chaperone, and costs $80 to rent. Since there are 640 students in the senior class that may be eligible to go on the trip, the officers must plan to accommodate at least 640 students. Since only 55 parents have volunteered to serve as chaperones, the officers must plan to use at most 55 chaperones. How many vehicles of each type should the officers rent in order to minimize the transportation costs? What are the minimal transportation costs? The officers should rent buses and vans to minimize the transportation costs.
4. Aardvark Car Rentals has two basic plans. One is to rent a car for $29 per day and then pay $.40 per mile. The second is to rent a car for $89 for the first day and then pay $49 for each subsequent day with unlimited mileage. Frank expects to drive a car about 500 miles total, but he has no idea how many days he’ll need it. (He might need it for 2 days, but he could see needing it for as many as 10 days.) Make a systematic list to help him decide which plan to use, showing which plan is best for each number of days up to 10.

MAY I ASK FOR THE SOLUTIONS AND ANSWERS OF NO. 22 to 26 Thank you! ABC Corporation resells one type of candle. It has 250 working days. Each day, it sells an average of 500 boxes but may sometimes sell a maximum of 600 boxes. The supplier takes an average of 5 days to deliver the order. During busier times, the supplier may take 7 days. Based on ABC’s records, ordering cost average P400 per order. Storage cost per box average P5 per year. There is also an opportunity cost of 1% per year for every peso invested in inventories. Each box of candles costs P450. If ABC would continue its current inventory management policy, it would keep 10,000 boxes as safety stock and order tendays-worth of inventory. (A) Reorder Point 1. What should be the reorder point in boxes? 2. How much would the normal lead time usage be? 3. How much should ABC keep as safety stock? (B) Economic Order Quantity 4.

The student chapter of Philippine Society of Mechanical Engineers is planning a 6-day trip to the National conference in North of Luzon. For transportation the group will rent a car from either the Motor Pool Corporation or a local car dealer. The Motor Pool charges Php 20.80 per km, has no daily fee, and the motor pool pays for the gas. The car dealer charges Php 1,500 per day and Php 11.2 per km, but the group must pay for the gas. The car's fuel rating is 40 km per gallon, and the price of the gas is estimated to be Php 96 per gallon. a. If the students anticipate driving 1,200 km total, from whom should they rent a car? b.At what point, in km, is the cost of both options equal? c. The car dealer has offered a special student discount and will give the students 50 free km per day, from whom should they rent a car. What is the new breakeven point?
The officers of a high school senior class are planning to rent buses and vans for a class trip. Each bus can transport 70 students, requires 5 chaperones, and costs $1,400 to rent.
