2. You have a factory that makes bikes and scooters. For bikes, you need 60 square feet of space per station to make bikes, it takes 20 minutes per bike to make one, and it costs you 80.26 dollars per bike; for scooters, you need 45 square feet of space per station, it takes 36 minutes per scooter to make one, and it costs you 85.19 dollars per scooter. You have 9000 dollars total to invest, 5000 square feet of floor space, and 50 hours in the week to make them. (a) What are the constraints of the linear inequality system as equations? Are there any implicit constraints? (b) Is this a maximization or minimization question? Why?. (c) If you make 130.50 dollars per bike and 102.50 dollars per scooter, how many of each should you make? How much money would you make?

Question
2. You have a factory that makes bikes and scooters. For bikes, you need 60 square feet of space
per station to make bikes, it takes 20 minutes per bike to make one, and it costs you 80.26
dollars per bike; for scooters, you need 45 square feet of space per station, it takes 36 minutes
per scooter to make one, and it costs you 85.19 dollars per scooter. You have 9000 dollars total
to invest, 5000 square feet of floor space, and 50 hours in the week to make them.
(a) What are the constraints of the linear inequality system as equations? Are there any
implicit constraints?
(b) Is this a maximization or minimization question? Why?.
(c) If you make 130.50 dollars per bike and 102.50 dollars per scooter, how many of each should
you make? How much money would you make?
(d) One of the scooter parts is now much more expensive, and it costs you 95.45 dollars now
to make one but you can only charge 107.99 dollars per scooter without losing too many
sales. How many of each should you make now? How much money would you make?
(e) All the constraints from the last problem are still true, but now there is a massive shortage
of bikes due to a supply issue that doesn't affect you, and you can sell bikes now for 150.95
dollars each. How many of each should you make, and how much money would you make?
