Answer: P(x) = -3x^2 + 49x - 105
Explanation:
The revenue accrued is the total income from sales or services rendered irrespective of the cost of purchase, production or rendering of the service. It means that revenue is the sum of cost and and profit.
From the information given, the revenue is expressed as a function,
Revenue = R(x)=x(65-3x) = 65x - 3x^2
The cost function is expressed as
C(x)=105+16x
Revenue = Profit + Cost
Therefore,
R(x) = P(x) + C(x)
65x - 3x^2 = P(x) + 105+16x
P(x) = -3x^2 + 65x - 16x - 105
P(x) = -3x^2 + 49x - 105
