1. Add a new product: Macs juice center, located near the university, serves as a gathering place for the universitys students. It sells orange juice at a contribution of $0.60 per bottle. Mac is considering selling sandwiches. He analyzed the following costs of adding sandwiches:

Per month		Per Sandwich
Monthly fixed costs:		Variable expenses:
Wages of cook	$ 1,200	Bread	$0.20
Other	$ 300	Vegetables	$0.60
Total	$ 1,500	Total	$0.80

Mac planned a selling price of $1.20 per sandwich to lure many customers. He thinks atleast 60 extra bottles of orange juice can be sold each day because he has sanwiches available. Assume 30 days in a month.

How many sandwiches should he sell on average each day for it to be worthwhile for Mac to expand into sandwiches?
