i JUST need help with this question.
16. Elizabeth and Sara 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 $5.50 off the cost. Margaret paid the rest, which came to $14.25. Each Ferris wheel ticket was $4.50, and a snow cone was $3.00. What was the cost for cotton candy?
