Given the data from the question, the first 12 cupcakes cost $2.00 each, and all cupcakes after that cost $1.00 each (Option A)
How to determine the price of each of the first 12 cupcakes
From the graph,
12 cupcakes = $24
Therefore,
1 cupcake = 24 / 12
1 cupcake = $2
Thus, for the first 12 cupcakes, each cost $2
How to determine the price for each of the remaining cupcakes
From the graph, we can determine the price of each of the remaining cupcakes as illustrated below:
18 - 12 = 6 cupcakes
30 - 24 = $6
Thus,
6 cupcakes = $6
Therefore,
1 cupcake = 6 / 6
1 cupcake = $1
Thus, we can conclude that, the first 12 cupcakes cost $2.00 each, and all cupcakes after that cost $1.00 each (Option A)
