The cost function is an illustration of a linear function
The equation of the cost function is C(x) = 35 + 0.5x
The given parameters are:
-- the cost of renting a cooler
--- the rate per bottle
Assume the number of bottles in a cooler is x.
The cost function for the bottles in a cooler would be:

So, we have:

Evaluate the products

Hence, the equation is

I'm ASSUMING that we're talking about Three Ordered Ordered Pair Solutions.
If so, the answer is (0,−1),(1,2),(2,5).
N*3.25=325.00
N=325.00/3.25
N=100
