A company represents its sales, since sales, since it's opening the function V (6) = 2000, using 1a 20€ +800€ + 300 84² + 10€ +100, the year where V is the total of sales, in millions of dollars, and t is the number of years since 2000 a) How much were the sales in 2000? b) What does the function. amount. the function predict about the of sales many years from now? Explain. c) Algebraically determine the years when the sales are $9500000
