A campus student group is raising funds for charity by selling cups of boba tea. The expenses incurred by this student group are the cost of materials, estimated at $2 per cup (tea, boba, milk, sugar, cups, the big honking straws, napkins, etc.) and the $150 cost of renting the brewing and cooking space. The group will charge students $4 for each cup.a. Write down the associated cost, revenue, and profit functions. b. How many cups of boba must they sell to break even?c. What profit (or loss) results from the sale of 50 cups?
The manager of a university bookstore is trying to determine whether or not to advance purchase
copies of a popular textbook. Her uncertainty is caused by the changing popularity of the course

Draw a decision tree to represent this situation. (critical to be shown in Excel submission).
The cost of operating a bus involves the cost of gasoline , the driver's wage
and other maintenance cost.
Assume that the cost of Gasoline is $ 1.25 per litre , the driver earns
$ 45 per hour , and maintenance cost is $ 0.18 per kilometre.
If the fuel efficiency of the bus traveling at 80 Kilometres per hour is
9.6 litre per 100 kilometres, determine the cost of operating the bus
(in Dollars) over a distance of 400 Kilometres.
Enter your answer without units.
Enter an integer or a fully reduced fraction such as 104 , 216 , 2056/7. etc.
