An accountant finds that the gross income, in thousands of dollars, of a small business can be modeled by the polynomial −0.3t 2 + 8t + 198, where t is the number of years after 2010. the yearly expenses of the business, in thousands of dollars, can be modeled by the polynomial −0.2t 2 + 2t + 131.
a. find a polynomial that predicts the net profit of the business after t years.
b. assuming that the models continue to hold, how much net profit can the business expect to make in the year 2016?
i know that the equation is -0.1t^2+6t+67, but i don't know how to find part b.
