Given:
Cost function c(x) = I0x+13
Profit Function p(x) = -0.3x² + 47x - 13
Find: revenue function r(x)
Solution:
To solve for the revenue function, simply add the cost and the profit function.
Eliminate the parenthesis.
Rearrange the terms according to their degree.
Combine similar terms.
Therefore, the revenue function r(x) is -0.3x² + 57x or by commutative property, the revenue function R(x) = 57x - 0.3x². (Option 3).
