Answer:
(B) $5.25
Step-by-step explanation:
We can create an equation to represent this problem.
Let's assume is the cost of a ferris wheel ticket,
is the cost of a snow cone, and
is the cost of a cotton candy.
We bought two ferris wheel tickets, one snow cone, and one cotton candy. After a discount of 6 dollars, the price was 12.75.
This makes the equation
Since we know the value of each ferris wheel ticket and the snow cone, we can simplify our equation by substituting in these values.
We can now subtract 7.5 from both sides to get the value of , the cotton candy price.
So the cotton candy cost $5.25.
Hope this helped!
