Revenue from single-day ticket sales at a local amusement park can be modeled by the function y=-x2+11x+42 and revenue from season pass sales can be modeled by the function y=-5x+81, where x represents the number of months past January and y represents the total revenue in tens of thousands of dollars.

Algebraically, determine after how many months the revenue from single-day ticket sales will equal the revenue from season pass sales. (The first time it occurs)

How much revenue will they have earned at this point in time from single-ticket and season pass sales?

Lots of points!

Step-by-step explanation:

(a) The revenue from sales will be equal when ...

  -x^2 +11x +42 = -5x +81

  0 = x^2 -16x +39

  0 = (x -13)(x -3)

According to this model, sales will be even after 3 months and after 13 months. The first time it occurs is after 3 months.

(b) Sales of each media at that point in time will be ...

  y = -5x +81 = -5(3) +81 = 66 . . . . tens of thousands of dollars

$660,000 will be earned from sales of single-tickets and from season pass sales, for a total of $1,320,000.

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

the answer is d on edge
