Question

PLEASE HELP!! The first answer WITH STEPS gets BRAINLY!

Answer 1

Answer:

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 value

Answer 2

=Mr.Lehmans hourly rate for labor is 20$

=30+40=70-50=20
