I need help answering the following questions

Once you have built the model, use it to answer Jake's questions about his business. Treat each situation as a separate scenario. All comparisons should be made to the original assumptions.

1. Save a copy of your original model to a new spreadsheet called "supplier cost increase". Say the supplier is expected to increase the cost of the products by 20%. What is the new operating income? What is the new WACM%? What is the new MOS%? Briefly explain your findings to the client.

2. Save a copy of your original model to a new spreadsheet called "new sales mix". Say the monthly sales volume is now expected to be 175 "Treat-times" and 125

"Launch-its" (same total units, but a different sales mix). What is the new operating income? What is the new WACM/unit ? Given this sales mix, how many units (in total) will Jake need to sell to earn his target profit? Briefly explain your findings to the client.

3. Save a copy of your original model to a new spreadsheet called "alternative contract". Say Jake's employee wanted to negotiate a different work contract: $1,500 per month plus 5% of revenue. Given his original sales volume and mix, how would this contract have changed Jake's operating income? What is the new operating leverage factor? What is the new expected percentage change in operating income if volume increases as expected in the future? Briefly explain your findings to the client.
