Gallons! gallons!! GALLONS!!! GALLONSSS!!!! hahaha. They're all the same so C. gallons. :).....xD
Answer:

Step-by-step explanation:
We have been given that the variables y and x have a proportional relationship, therefore, we can represent the relationship between x and y as:
, where k is proportionality constant.
Let us substitute x=3 and y=15 in above equation to find the value of k.


Now let us substitute k=5 and y=4 in our proportionality equation to find the corresponding value of x.



Therefore, the value of x will be 0.8, when y equals to 4.

The length of vacation or time when each resort cost about the same is 32 days.
<h3>How to calculate the time?</h3>
From the information given, it was stated that Blue Water Resorts offers a vacation package starting at $1350 for a 4 night stay and each additional night adds $149 to the package price. Sea Breeze Resort offers a similar package, starting at $900 for a 4 night stay.
The equation to compute the time will be:
1350 + 149x = 900 + 135x
Compute like terms
149x - 135x = 1350 - 900
14x = 450
x = 450/14
x = 32
