Answer:
Proportional: Mike, a plumber charges $5 per hour for his service.
Non-proportional: Mike charges a initial cost of $10 plus $3 for each hours of service.
Step-by-step explanation:
Let us assume that Mike, a plumber charges $5 per hour for his service.
So, the number of hours (h) of service and the total charge (C) are proportional, which is
C(h) = 5h ....... (1)
If the condition changes like, Mike charges an initial cost of $10 plus $3 for each hour of service.
Here, the equation that models the situation is
C(h) = 10 + 3h .......... (2)
Now, relation (1) is non-proportional. (Answer)
50 = 25 + 0.50w - 0.25w
50 = 25 + 0.25w
50 - 25 = 0.25w
25 = 0.25w
25/0.25 = w
w = 100.
