The tickets for the Ferris wheel were $5 each, so for both Ella and Margaret, the total cost for their tickets was 2 * $5 = $<<2*5=10>>10.
Ella's snow cone cost $3.50 and she had a $6 certificate to use towards it, so her actual cost came down to $3.50 - $6 = $<<3.5-6=-2.5>>-2.5.
The total cost for everything came down to a negative cost of $-2.5 (Ella's negative amount) + ($12.75 paid by Margaret $) = $-2.5 + $12.75 = $<<-2.5+12.75=10.25>>10.25 as the overall cost.
That leaves a balance of $10.25 - $10 (the cost for the Ferris wheel for both Ella and Margaret) = $0.25 for the cost of the cotton candy. Answer: \boxed{0.25}.
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 a snow cone was $3.50. What was the cost for cotton candy?
