Answer:the maximum number of ccf Jake can use if he wants his bill to be no more than $58.00 is $15.3
Step-by-step explanation:
Let x represent the number of ccf of water that Jake uses in a month.
Jake's water bill is $24.40 per month plus $2.20 per ccf (hundred cubic feet) of water. This means that if she uses x ccf of water in a month, her total water bill would be
24.40 + 2.2x
Therefore, the maximum number of ccf Jake can use if he wants his bill to be no more than $58.00 would be
24.40 + 2.2x ≤ 58
2.2x ≤ 58 - 24.4
2.2x ≤ 33.6
x ≤ 33.6/2.2
x ≤ 15.3

Let's assume
length of rectangle is x
width of rectangle is y
now, we can draw rectangle
now, we can find fencing length
we are given
total fencing length=400
so, we can set them equal
now, we can solve for y
now, we can find area
Area=length*width
we can plug back y
we have to maximise area
For maximising area , firstly we find derivative of area
and then we can set derivative =0 and then we solve for x
so, firstly we will find derivative
now, we can set it to 0
and then we solve for x
now, we can find y
so, dimensions are
length is 100 feet
width is feet.............Answer
