Lemon Juice (cups)    5    10    20
Servings                   35     70  140

The two quantities are proportional. Lemon Juice (cups) is the x-value ; while servings is the y-value.

  35 ÷   5 = 7
  70 ÷ 10 = 7
140 ÷ 20 = 7

The constant of proportionality is 7.

The equation would be: y = 7x

The vertex represent a minimum

In the context of this problem

The vertex represent the minimum amount of profit

In this problem the vertex is the point (0.4,-4)

0.4 represent -----> 0.4(1,000)=400 users
