Answer:
The crossover point for Time 
Step-by-step explanation:
From the question we are told that
The total rooms rented for the year is 
Time's fixed cost is r = $61,000
Time's variable cost is
$12.5 per room
Duffy's Maid Service fixed cost is
$25,000
Duffy's Maid Service variable cost is
$18.00 per room
The cross over point for Time is mathematically represented as

substituting values

Answer:
The equation of the axis of symmetry is equal to

Step-by-step explanation:
we have

This is the equation of a vertical parabola written in vertex form open upward (because the leading coefficient is positive)
The vertex represent a minimum
The axis of symmetry is equal to the x-coordinate of the vertex
we have that
The vertex is the point (10,-6)
The x-coordinate of the vertex is 10
therefore
The equation of the axis of symmetry is equal to

The scale used to represent the distance between two cities is 1 inch= 6 miles, where the actual distance between the cities is 24 miles.
If the scale in a different map is 1 inch= 1 mile then the separation in the graph should be 24 inches.
Step-by-step explanation:
- Given that the distance between two cities on a map is 4 inches and the original distance between these two cities are 24 miles. Hence, to find the scale is to divide them, so you get 6
- then, 1 inch = 6 miles, to find the inches if the scale 1 inch = 1 mile, multiply it with the original distance between these two cities. Hence, it is 24 inches
