Yesterday, Consuela bought some fudge and caramels for $5.25. She bought 2 pieces of fudge at 50 cents a piece and some caramels at 25 cents each. She gave some caramels to her friend Carrie. Now she has 2 pieces of fudge and 10 caramels. If consuela did not eat any candy yet, how many caramels did Carrie receive?​
