Please help!!! Ella and Margaret were at a carnival. They each got a ticket for the Ferris wheel. Ella got a snow cone, and Marg
seraphim [82]

Answer:

(B) $5.25

Step-by-step explanation:

We can create an equation to represent this problem.

Let's assume f is the cost of a ferris wheel ticket, s is the cost of a snow cone, and c 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

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

We can now subtract 7.5 from both sides to get the value of c, the cotton candy price.

7.5 + c - 7.5 = 12.75 - 7.5\\\\c = 5.25

So the cotton candy cost $5.25.

Hope this helped!
