Answer:
Step-by-step explanation:
For the A part of the question you have to find the hourly rate and the one time fee of both "A Plus Plumbing" and the "Quality Plumbing". To do this if we look at the chart for "A Plus Plumbing" we see at zero hours it would cost $80 and for "Quality Plumbing" it starts at 150, so for "A Plus Plumbing" it would cost 80 flat fee and 150 flat fee for Quality Plumbing. For Hourly we can do 140 - 80 (flat fee) = 60, meaning the hourly rate is $60, and if we do 200 (after 1 hour of work) - 150 (flat fee) = 50, meaning the hourly rate $50.
B
"A Plus Plumbing" we see at zero hours it would cost $80 and for Hourly we can do 140 (after 1 hour of work) - 80 (flat fee) = 60 (look at A for explanation).
C
For "Quality Plumbing" it starts at 150 flat fee and if we do 200 (after 1 hour of work) - 150 (flat fee) = 50, meaning the hourly rate $50. (look at A for explanation).
D
