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 ![2f + s + c - 6 = 12.75](https://tex.z-dn.net/?f=2f%20%2B%20s%20%2B%20c%20-%206%20%3D%2012.75)
Since we know the value of each ferris wheel ticket and the snow cone, we can simplify our equation by substituting in these values.
![2(5) + 3.50 + c - 6 = 12.75\\\\10 + 3.50 + c - 6 = 12.75\\\\7.5 + c = 12.75](https://tex.z-dn.net/?f=2%285%29%20%2B%203.50%20%2B%20c%20-%206%20%3D%2012.75%5C%5C%5C%5C10%20%2B%203.50%20%2B%20c%20-%206%20%3D%2012.75%5C%5C%5C%5C7.5%20%2B%20c%20%3D%2012.75)
We can now subtract 7.5 from both sides to get the value of
, the cotton candy price.
![7.5 + c - 7.5 = 12.75 - 7.5\\\\c = 5.25](https://tex.z-dn.net/?f=7.5%20%2B%20c%20-%207.5%20%3D%2012.75%20-%207.5%5C%5C%5C%5Cc%20%3D%205.25)
So the cotton candy cost $5.25.
Hope this helped!
