100x2 + 15,750x + 212,500 ≥ 243,600

in this activity, you’ll solve this inequality to find the minimum ticket price amy should charge to meet her minimum revenue goal.

part a

set the inequality greater than or equal to 0.

The minimum ticket price is $2.

Step-by-step explanation:

The inequality is given by  

- 100x² + 15750x + 212500 ≥ 243600

⇒ - 100x² + 15750x - 31100 ≥ 0

⇒ - 2x² + 315x - 622 ≥ 0

⇒ -2x² + 311x + 4x - 622 ≥ 0

⇒ (2x - 311)(2 - x) ≥ 0

Now, either (2x - 311) ≥ 0 and (2 - x) ≥ 0

⇒ x ≥ 155.5 and x ≤ 2, which is not possible.

Or, (2x - 311) ≤ 0 and (2 - x) ≤ 0

⇒ x ≤ 155.5 and x ≥ 2, which is a valid range of x-value.

Therefore, the minimum ticket price is $2. (Answer)

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
