Given

The question has missing details. However, I will solve on a general term.
A possible question could be to find the cost of purchasing (say 10 bottles).
To do this, we simply substitute 10 for p.
So:





i.e. $137.50 for 10 pint bottles
Another possible question is to calculate the number of pint bottles that amount to (say $70).
To do this, we simply substitute 70 for Price.
So:


Collect like terms


Divide both sides by 13.50

Add 2 to both sides



i.e. $70 will buy 5 pint bottles

The amount of work (or the rate) done by the first person is 1/21
r = 1/21
Cost = 15x + 2000
Earning = 35x
At break even, cost = earning
35x = 15x + 2000
20x = 2000
x = 100
100 rides are needed to break even.
Answer:
$15,339
Step-by-step explanation:
C(x) = 0.5x² − 100x + 20,339
Since this is a parabola, the minimum cost is at the vertex:
x = -b / (2a)
x = -(-100) / (2 × 0.5)
x = 100
So the minimum cost is:
C(100) = 0.5(100)² − 100(100) + 20,339
C(100) = 15,339
