Acme has three product lines which are Razor, elf, and cat. Info for the product lines are shown below

	Razor	Elf	Cat
Revenue	70,000	31000	24000
Variable Costs	36000	15000	15000
Fixed Costs
Service Support (can avoid if product is dropped)	12000	8700	6400
General (can avoid if product is dropped)	8600	7300	5400

Acme is considering replacing the elf and cat with a new product line: Ashton. the new line would be sold for 15/per unit with a per-unit varable cost of 8 and would have a required customer support cost of 14,700.

What is the minimum number of ashton units, that acme company would have to sell in order to justify replacing the elf and cyan products?
