Answer should be $174.91? if that isnt an option tell me and i will regroup
For this case we have the following polynomial:

What we must do for this case is to factor the polynomial, so that we have:
1) The number of bottles
2) the weight of each bottle.
We have then:

Answer:
A factorization that could represent the number of water bottles and weight of each water bottle is:

On the X-Y plane, the points p and r are on the vertical line X=x. Then the perpendicular (horizontal) line through p will have the equation Y=y. Points q on that line will have coordinates
... q(<anything>, y)
The answer is 68, Which should be correct
