Step-by-step explanation:
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:
1.5m + d = 24
Step-by-step explanation:
Each muffin costs $1.50.
m number of muffins cost m * $1.50 or 1.5m.
Each doughnut costs $1.00.
d number of doughnuts cost d * $1.00 or 1d or simply d.
The total cost of muffins and doughnuts is
1.5m + d.
We are told the total cost is $24, so we get
1.5m + d = 24
