Present economy studies are engineering economic analysis where alternatives for accomplishing a specific task are being compared. One example is the selection of design to analyze which design should be adopted that will be more economical in the long run. Design A will require 16 hours of lathe time and 4.5 of drill time per 500 units. Design B will require 7 hours of lathe time and 12 hours of drill time per 500 units. Php 930/hr - Operating cost of lathe including labor Php 845/hr - Variable operating cost of drill including labor Which design should be adopted? Explain, justify, show your solution, and present any evidence to back up your answer. (10 points)
