Break even problem.

Racer Scooters plans to sell a standard scooter for $54 and chrome scooter for$78. Purchases of the standard scooter are $36, and chrome are $50. Racer expects to sell two chromes scooters for every three standard scooters. Racer's monthly fixed expenses are $9, 680. How many of scooter must Racer sell monthly to breakeven, in units and in dollars? To earn a monthly profit of $6, 600? The solution should be shown using the contribution margin approach and the income statement approach to show breakeven to zero and to earn a monthly desired profit. You should also show/draw a graph or two, showing: breakeven point to zero, to desired profit, with lines showing revenues, fixed & variable cost, units and dollars, profit and loss areas
