As a treasurer of your school, you chair the committee to decide how the $20,000 raised by candy sales will be spent. Four kinds of projects have been proposed, and facts on each are shown below.

Project	# Requested	Unit Cost	Volunteers Needed (Person-days, each)
Basketball goals	12	$400	2
Encyclopedia sets	5	$750	0
Field trips	6	$300	3
Computer stations	20	$800	.5

Develop a goal-programming model that would represent these goals and priorities.

Priority 1:

Goal 1 - Spend the entire $20,000.

Goal 2 - Do not use more than 50 person-days of volunteer time.

Priority 2:

Goal 3 - Provide at least as many encyclopedias and computers as requested.

Goal 4 - Provide at least as many field trips as requested.

Goal 5 - Do not provide any more basketball goals than requested.
