Homework Answers

Answer #1
If downhill is produced, Hours
Total finishing time available per week 64
Finishing time per downhill ski 8
Maximum number of skis can produce per week ( 64/8 ) = 8 skis
Therefore, maximum profit by producing maximum number of downhill skis per week = 8 skis x $ 77 = $ 616
If cross-country skis are produced, Hours
Total manufacturing time available per week 18
manufacturing time per ski 2
Maximum number of skis can produce per week ( 18/2 ) = 9 skis
Therefore, maximum profit by producing maximum number of cross-country skis per week = 9 skis x $ 79 = $ 711
Conclusion; Company shall produce maximum number of corss-country skis by using maximum available manufacturing time available in a week.
