Step-by-step explanation:
To determine the amount of incremental guests needed to break even on a local store marketing event, you can use the equation given in option D: All of the above.
Option A suggests dividing Net Sales by the weekly cost of the billboard. This will give you the number of guests needed to cover the cost of the billboard.
Option B suggests multiplying MAVE/guest by AWGC. MAVE stands for Marketing Average Value Effect and AWGC stands for Average Weekly Guest Count. This equation will give you the incremental guests needed to break even.
Option C suggests dividing the weekly cost of the event by MAVE/guest. This will also give you the incremental guests needed to break even on the event.
