Answer:
see the explanation
Step-by-step explanation:
Let
x ----> number of usage days
y ---> the total charge monthly in dollars
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have


substitute

we have the ordered pair (13,41)
For x=13 usage days


therefore
That means----> Total charge in one month for 13 days of use is $41
C : katrin climbed 17 feet up a hill and went down 8 feet
Step-by-step explanation:
18 minutes in total.
4 1/2 minutes per pot.
so, all we need to do is find out how often 4 1/2 fits into 18. that is what division is for.
18 / (4 1/2)
4 1/2 = 2×4/2 + 1/2 = 8/2 + 1/2 = 9/2
18 / 9/2 = 18/1 / 9/2 = 2×18 / 9×1 = 36/9 = 4
