Given the above information in Q1, Shannon's wants to increase its sales to retailers by 20% in the next year. Management estimates that the incremental promotion program required to generate sufficient demand to boost sales by 20% will be: Shannon's will need to hire an additional salesperson (paid a salary and commission) and provide some added administrative support.
