In Tuftsville, everyone lives along Main

Street, which is 10 miles long. There are

1,000 people uniformly spread up and down

Main Street, and every day they each buy

a fruit smoothie from one of the two stores

located at either end of Main Street. Customers

ride their motor scooters to and from

the store using $0.50 worth of gas per mile.

Customers buy their smoothies from the store

offering the lowest price, which is the store's

price plus the customer's travel expenses

getting to and from the store. Ben owns the

store at the west end of Main Street and Will

owns the store at the east end of Main Street.

b. If Ben charges $3 per smoothie, what

price would enable Will to sell 250

smoothies per day? 500 smoothies per

day? 750 smoothies per day? 1,000

smoothies per day?
