The Audubon Society at Enormous State University (ESU) is planning its annual fund-raising "Eat-a-thon." The society will charge students 90¢ per serving of pasta. The only expenses the society will incur are the cost of the pasta, estimated at 20¢ per serving, and the $350 cost of renting the facility for the evening.

(a) Write down the associated cost function C(x) in dollars.
C(x) =



Write down the revenue function R(x) in dollars.

c(x) = 350 + .20 x

(a) The cost function C(x) in dollars is given by:

C(x) = (cost of pasta per serving) * x + (rental cost)

C(x) = 0.20x + 350

(b) The revenue function R(x) in dollars is given by:

R(x) = (price per serving) * x

R(x) = 0.90x

(a) The cost function C(x) in dollars can be calculated by adding the cost of pasta per serving (20¢) and the cost of renting the facility ($350).

C(x) = 0.20x + 350

(b) The revenue function R(x) in dollars can be calculated by multiplying the number of servings (x) by the price per serving (90¢).

R(x) = 0.90x
