(1 h)/(11 qt) * (12 qt)/(1 barrel) * (120 barrels/pickup) * (1 day)/(24 h)
.. = 12*120/(11*24) day/pickup
.. = 5 5/11 days/pickup
120 barrels will be filled every 5 5/11 days. Some trips will be 5 days apart, some trips will be 6 days apart.
We take the function as a sequence
Term 1 ⇒ 5
Term 2 ⇒ 4
Term 3 ⇒ 3.2
Between terms, there is a common ratio of ⁴/₅
We get it from here:
Term 2 / Term 1 =

Term 3 / Term 2 =

=

When a sequence has a common ratio between term, the sequence is a Geometric Sequence

Where

is the first term,

is the common ratio, and

is the term number
We have:

and

The formula for the function is
The length of the bedroom exists at x = 9 and y = 6.
<h3>How to estimate the length of the bedroom?</h3>
From the given information, we get
Then 
Solve this for x.
simplifying the value of x we get
Equate (1/9) to 1/x.
x = 9 (feet).
Convert 1.5 inches to feet using a proportion:

Solve this for y.
simplifying the value of y we get
(1/4)y = 3/2
Multiply both sides of the equation by 4.
y = 6
Therefore, the length of the bedroom exists at x = 9 and y = 6.

All real numbers.
No matter what you plug in, there will always be a corresponding y - value.
The answer is b because youre multiplying 3 and 4 but the 4 stays in the same spot!
