Anyone know how to figure this out?

  (a) f(x) = 110x -x^2

  (b) $55

Step-by-step explanation:

You figure out part (a) by following directions. Multiply (110 -x) by x. Use the distributive property to simplify it:

  f(x) = 110x -x^2

You know that the vertex of a parabola is on the line of symmetry, and that any two points with the same y-value are located symmetrically about that line. The function f(x) = x(110 -x) is zero for x=0 and for x=110. The vertex (maximum) of the function will be located halfway between these values, at ...

  x = (0 +110)/2 = 55

She should charge $55 to maximize her revenue.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
