Answer:
a) 40$ b) 7600
Step-by-step explanation:
In my opinion, the best way to go about this is to simply start by doing 20×300, 25×270, 30×240, etc. Once I reached 40, I realized that my revenue was going down after it, so I saw that a 40 dollar starting price would being in more money. 40×190 - (the amount of students who will buy at that price) equals 7600, which will be your maximum revenue. I hope i could help, good luck.
