Jake has hired an employee to work the trade show booths. The work contract is $1,000 per month plus a commission equal to 10% of revenue. Jake will also spend $500 per month on trade-show entry fees. Jake is purchasing the products from a supplier in Mexico. Launch-its cost $1 each; Treat-times cost $7 each. Shipping and handling on the Launch-its will cost $2 each; Shipping and handling on the Treat-times, which are heavier, will cost $8 each. The shipping and handling costs will be paid by Jake, not the customer.

Assume Jake expects to sell 200 Launch-its and 100 Treat-times during his first month of operations (June).

Jake's financial goal is to earn an operating income of $8,000 per month. He believes volume may grow at a rate of 5% a month.
