PLEASE HELP!! The first answer WITH STEPS gets Mr. Lehman is a piano tuner. He charges his clients a fixed amount for a house call plus his labor which is based on an hourly rate. The graph below shows how much Mr. Lehman charges as a function of the time required to tune a piano

Which of the following best represents Mr. Lehmans hourly rate for labor?

A. 10$
B. 15$
C. 20$
D. 25$

=Mr.Lehmans hourly rate for labor is 20$

=30+40=70-50=20

The Answer is 15$

You'd need to get the slope

it tells us how he charges with respect to Time

So picking any Point on the graph. Let's say (0,10) and (2,40)

m(slope) = y2-y1/x2-x1

= 40-10/2-0

=30/2

= 15$

Picking other points would still give this valye

step-by-step explanation:

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
