The prices of Coke and Popcorn are $0.50 and $1.00, respectively, and not $1.00 and $0.50, respectively because of the inverse relationship of Coke units bought and Popcorn units bought.
What is an inverse relationship?
An inverse relationship implies that higher values of one variable are associated with lower values of another comparable variable.
This situation is further graphically illustrated as shown and explained below:
When 20 Coke units are bought, 0 Popcorn unit is bought. When 10 Popcorn units are bought, 0 Coke unit is bought.
From the graph, the points can be plotted as follows:
Points: (0 popcorn, 20 coke) and (10 popcorn, 0 coke)
Data and Calculations:
Money income = $10
Price of Coke = $0.50
Price of Popcorn = $1.00
Using the $10, the units of Coke bought = 20, since $10 = ($0.50 x 20)
Using the $10, the units of Popcorn bought = 10, since $10 = $1 x 10)
Thus, an inverse relationship exists between the units of Coke and Popcorn that one can buy, given the money income and the prices of the goods.
