Group Project MATH 221, Spring 2015.

Instructions

? Students are required to organize themselves in group.

? Once organized, the group members HAVE to sign-up in the groups created on Blackboard. The group number should correspond to the project number (you select from the list below). For example, the students who select project one should sign-up in group one on blackboard.

? The Group size can be up to a maximum of 5 students.

? Each group is required to select a project from the following list.

? Only one group can work on a specific project (in other words, two groups CANNOT work on the same project).

? All projects are subject to the same set of questions listed at the end.

? The report on the project shall be due one week before the end of classes.

? Please follow the schedule below:

Projects List

Project #1: The demand function for a monopolist’s product is ??=700-2?? and the average cost per unit for producing ?? units is ??¯=??+100+ 1000?? , where ??= price, and ??= quantity demand.

Project #2: Consider the demand function is ??=10000-80?? and the total cost function is ??=0.004 ??3+20 ??+5000.

Project #3: The demand function for product is ??=-??+108 and the total cost per unit for producing ?? units is ??=3??2+8??+300 , where ??= price, and ??= quantity demand.

Project # 4: The demand function for product is ??=-5??+4500 and the total cost per unit for producing ?? units is ??=3??2+300??+20000 , where ??= price, and ??= quantity demand. Project # 5: Suppose that the cost function for a product is given by ??(??)=0.05??2-10??+1000. The demand function for product is ??=-5??+200.

Project #6: Suppose that the dollar cost of producing q appliances is ??(??)=500-100??+0.4??2 and the demand function is given by =20-0.02?? .

Project #7: Suppose that the dollar cost of producing q appliances is ??(??)=1500-90 ??+0.3??2 and the demand function is given by ??=25-0.02??

Project #8: The demand function for a monopolist’s product is ??=800-?? and the average cost per unit for producing ?? units is ??¯=??+100+ 500?? , where ??= price, and ??= quantity demand.

Project #9: The demand function for a monopolist’s product is ??=800-10?? and the average cost per unit for producing ?? units is ??¯=??+10+ 1100?? , where ??= price, and ?? = quantity demand.

Project #10: The demand function for a monopolist’s product is ??=800-10?? and the average cost per unit for producing ?? units is ??¯=??+100+ 1300?? , where ?? = price, and ?? = quantity demand
