For Nos. 13-15: In manufacturing a certain machine part, it is necessary to make four holes in each part. Each hole will require one minute if drilled with the aid of a jig. The drill jig would cost P1,500 to construct and the drill press operator is paid P32.50 per hour. Overhead costs on the drill press are P20 per hour. The four holes can be made in 20 seconds on a punch press, but a die costing P3,000 will be required. It requires 30 minutes to set up the die on the press and the same number of minutes to tear it down when the job is completed. Overhead charges for the punch press are P35.00 per hour. The press operator receives P30.00 per hour and the set-up man is paid P50.00 per hour. Determine the comparative cost for 1000 parts and the number of parts to be made for equal costs. 13.
