Question

Gatorade/Tropicana North America, a subsidiary of PepsiCo, produces fruit juices and other flavored beverages. Based on data from 1999 to 2001, the net sales (revenue) of Gatorade/Tropicana North America may be modeled by
R(t) = -107t2+496t+3452 million dollars
and the operating profit (earnings before interest and taxes) may be modeled by
P(t) = −18.5t2 + 85.5t + 433 million dollars
- where t is the number of years since 1999.
What was the profit in 2000?

Use the equation found in question 6 to find the costs in 2000.
