Luxury Pens Manufacturing makes two models of permanent markers. Requirements for each lot of markers are given below:

Resources	Fliptop Model (F)	Tiptop Model (T)	Available
Plastic	3	4	36
Ink Assembly	6	5	40
Molding Time	4	3	27

The profit for Fliptop model is $6000 per lot while the profit for Tiptop model is $4000 per lot. Let F = the number of lots of Fliptop pens to produce and T = the number of lots of Tiptop pens to produce. Formulate and solve the integer linear programming problem then answer questions #3-5.

The objective function can be expressed as ________.

Min: $6000F + $4000T

Max: $6000F + $4000T

Min: $4000F + $6000T

Max: $4000F + $6000T

Use the previous integer linear programming (Luxury Pens Manufacturing). Which of the following is not a constraint for this problem?

F, T integer

4F + 3T <=27

3F + 4T <= 36

F, T <= 0

Use the previous integer linear programming (Luxury Pens Manufacturing). The optimal solution for Luxury Pens Manufacturing is to make ________ lots of Fliptop model and ________ lots of TipTop model.
