Answer :
Function of the Annual Profit of the company, say P is P(t) = ( 1.1 )t² + 12.2 t + 87 where t is represent time in years.
Function : is an expression which represents the relationship between two variable where one is dependent and other one is independent.
Annual Cost is the total amount of expenses a company (organisation) spends on an employee during one year.
we have given, Cost C ( in thousand of dollar)
and revenue R (in thousand of dollar) for a company. Cost function C, is C = 254 - 9t + (1.1)t² where t time in year .
and Revenue function R = 341 - 3.2t
the value t = 9 represents 9 years. If P represent the Annual profit then
P = R - C i.e., P = 341 - (3.2)t - 254 - 9t + (1.1)t²
= (1.1)t² - (12.2)t + 87
Hence, the annual profit (in thousand dollars) is
P = (1.1)t² - (12.2)t +87 .
