Question

An average of 70,000 people visit Riverside Park each day in the summer. The park charges $12.00 for admission. Consultants predict that for each $1.00 increase in the entrance price, the park would lose an average of 2,500 customers per day. (a) Express the daily revenue from ticket sales, R as a function of the number of $1.00 price increases, x. R=f(x)= (70000-2500x)(12+x) equation editorEquation Editor (b) What ticket price maximizes the revenue from ticket sales?

Answer 1

Answer:

The price that maximizes the revenue is $20

Step-by-step explanation:

(a) Express the daily revenue from ticket sales, R as a function of the number of $1.00 price increases,

R(x) = (70000-2500x)(12+x)

(b) What ticket price maximizes the revenue from ticket sales?

The ticket price that maximizes the revenue is associated with the x of the vertex of the parabola.

R(x) = (70000-2500x)(12+x) = 840000 + 70000x - 30000x - 2500x² =

-2500x² + 40000x + 840000

x vertex = -b/2a = -40000/2.(-2500) = 8

12+8 = 20
