Question:

Ames Manufacturing Plant produces two different replacement parts for dishwashers. During a normal shift, they have 7 hours of time available on their main fabrication machine. The machine will process 40 of Part X in an hour and 25 of Part Y. Each Part X requires .5 hours to assemble and each Part Y requires .4 hours. Ames has 64 hours if labor available on this line each shift. The painting booth can handle 40 parts per hour and can be used a max of 6 hours per shift. Ames has a $45 profit margin for Part X and $40 for Part Y. Below you can see the spreadsheet model with the optimal profit maximizing production plan and the sensitivity analysis. Answer the questions based on this output.

Time is in hours
Machining: Part X:.03 Part Y:.04. Available:7
Labor: Part X:.5 Part Y:.4 Available:64
Painting: Part X:.03 Part Y:.03 Available:6
Unit Profit: Part X:$45 Part Y:$40

Production Plan: Part X:0. Part Y:160

LHS RHS
Machining: 6.4 <= 7
Labor: 64<= 64
Painting: 4<= 6

Total Profit: 6400
