The Hydro water department has a monthly service charge of $13.90 and a volume charge of $1.45 for every 100 cubic feet of water

.
The total monthly cost is equal to the service charge plus the charge for the volume used during the month. If we let x represent the number of cubic feet of water (in hundreds) and y represent the total monthly cost, then we have:
total monthly cost = volume charge + service charge
y = 1.45x + 13.90

If the Johnson family used 200 ft3 more water this month than last month, then they can expect
A. an increase in their water bill of $2.90.

B. an increase in their water bill of $27.80.

C. a decrease in their water bill of $2.90.

D. a decrease in their water bill of $27.80.

Answer: A

Step-by-step explanation:

In this question, you can disregard the initial $13.90 cost because we're only looking for an INCREASE in price. If the Johnson family used 200 cubic feet MORE of water, we need to multiply 2 * 1.45 which gets us 2.90. We multiply 2 by 1.45 because 200 represented in x is 2, since x is represented in hundreds.

Answer:

Since the slope of the line is (31/4 - 25/4) / (5/4 - 3/4) = 3 that means that for every 1 that x increases, y increases by 3 so an example could be 1 3/4 for x and 9 1/4 for y.

What is the answer 2n-3/5= 5 <br> n= what?
motikmotik
So you need to isolate the N right?
So what you want to do is add -3/5 to both sides to remove it from the left side. making it
2n=5+3/5 now all you need to do it isolate the N by divinding it by 2 on each side
n=5+3/5
         /2
the 5+3/5 is divided by 2.
so N equales 5+3/5----/2
