Mixture B is the right answer
The graph described is the graph of a quadratic function.
The x-intercept of the function is at; (8, 0).
<h3>What type of function is described by the graph?</h3>
It follows from the description box of the graph that it begins in the third quadrant, and rises through a series of points in the first quadrant before it exits the first quadrant.
Hence, it follows that the graph is a quadratic function and its x-intercept is at point; (8,0).

The slope of the line can be interpreted that with each additional hour, nearly 18 customers are served; option B
<h3>What is the slope of a line?</h3>
The slope of a line is the ratio of climb to that of run
Slope = change in y/change in x
The given graph is a graph of the number of hours an employee spends working a checkout line (x), against the number of customers served (y).
The slope of the graph can be written as follows:
Slope = change in the number of customers served/change in the number of hours an employee spends working
Therefore, the slope of the line can be interpreted that with each additional hour, nearly 18 customers are served.
In conclusion, slope of a line is ratio of change in y to change in x.

7/4 is the answer to your question
Answer:
Step-by-step explanation:
let a=Ann's amt., b=Betty's amt.
a=2b+9
b+2b+9=60
3b+9-9=60-9
3b=51
b=$17
a=34+9=$43
