Final answer:
Walls Tavern's annual sales for lunch and dinner can be calculated by multiplying the number of seats, seat turnover rate, average check, days of operation, and weeks in a year. The guest count per period can be calculated by multiplying the number of seats by the seat turnover rate.
Step-by-step explanation:
To calculate the annual sales for lunch and dinner at Walls Tavern, we need to multiply the number of seats by the seat turnover rate and the average check for each meal.
a. Annual sales for lunch = 80 seats * 1.7 turnover rate * $8.50 average check * 6 days * 52 weeks = $50,232
Annual sales for dinner = 80 seats * 1.5 turnover rate * $12.00 average check * 6 days * 52 weeks = $69,888
b. To calculate the guest count per period, we need to multiply the number of seats by the seat turnover rate.
The guest count per period for lunch = 80 seats * 1.7 turnover rate = 136
The guest count per period for dinner = 80 seats * 1.5 turnover rate = 120
