Ella and Margaret were at a carnival. They each got a ticket for the Ferris wheel. Ella got a snow cone, and Margaret got a cotton candy. Ella had a certificate for $6 off the cost. Margaret paid the rest, which came to 12.75. Each Ferris wheel ticket was $5, and the snow cone was $3.50. What is the cost of the cotton candy? A. $5.00 B. $5.25 C. $2.50 D. $7.25

(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!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
