What I have so far from feedback is:
calculations are correct so far but the breakeven points are missing as well as target profit orders necessary and revenues. writeup missing.
The requirements:
1) Discuss the pros & cons of each sales channel
2) compute contribution margin for each channel
3) compute break even point (in terms of number of orders and dollars) for each distribution channel
(HINT  - Fixed costs are all trade show expenses.  Use depreciation for the booth as a fixed cost.  The booth cost should be considered an investment not a fixed cost)
4) Calculate the number of orders at a target profit of $100,000
5) Calculate the profitability for both the low and high order estimates
Calculations MUST be done on EXCEL. Writeup MUST be done on WORD.
