Beasley’s Chili Classic

Each fall, Beasley’s Root Beer sponsors the annual Chili Classic. Five different cooksprepare large pots of chili. The customers line up with bowls for chili and glasses for Beasley’s root beer.

Toots Beasley brews root beer for the event. He has learned from experience that a customer drinks a quart of root beer for each two tablespoons of chili powder consumed. Further, Toots knows that the number (b) of bowls of chili sold by a cook is related to the number (t) of tablespoons of chili powder used in each bowl of chili by the equation: b = -t² + 7t + 22.

Willy McNilly uses 3 tablespoons of chili powder in every bowl of his chili, Connie Carney throws in 5 tablespoons of chili powder in every bowl of her chili, Prudence Pennywhistle uses no chili powder at all in her chili, David Chung tosses 4 tablespoons of chili powder in every bowl in his chili, and Voratia Vesuvius stirs 7 tablespoons of chili powder in every bowl of her chili.

How many quarts of root beer does Toots sell at 85¢ a quart? Show all work.
