Answer:
a. $45 an hour
b. 5.25 hours
Step-by-step explanation:
a. The plumber charges $75 per job, so it is irrelevant to the number of hours they work. 45(h) is $45 multiplied by the number of hours they work.
b.
First, plug the numbers into the equation, the cost being C(h):
311.25 = 45(h) + 75
Next, subtract $75 as it is a set price that is always payed:
236.25 = 45(h)
Then, divide both sides by 45 to find how many hours were worked:
h = 5.25
Hours = $5.25
Answer:
8x - 20
Step-by-step explanation:
3(x - 6) + 4 + 5x - 6 
Distribute 3 to (x - 6)
3(x) - 3(6) + 4 + 5x - 6
3x - 18 + 4 + 5x - 6
Simplify:
3x + 5x - 18 + 4 - 6
8x -18 - 2
8x - 20
