A company producing a standard line and a deluxe line of fidget spinners has the following time requirements (in minutes) in departments where either model can be processed.

​	Standard	Deluxe
Stamping	0.3	0.4
Extruding	0.25	0.5
Fidget Testing	1	1.5

The standard models contribute $2 each and the deluxe $3 each to profits. Because the company produces other items that share resources used to make the fidget spinners, the stamping machine is available only 15 minutes per hour, on average. The extruding unit has 20 minutes available each hour. There are two ADHD certified inspectors for fidget testing, but their availability is only 45 minutes per hour because they're easily distracted.

Let S = number of standard fidget spinners produced per hour
D = number of deluxe fidget spinners produced per hour
