Maggie bought 2 boxes of cupcakes for her daughters. She ate one cupcake herself and told her 3 daughters to share the remaining cupcakes equally. If there were c cupcakes in each box, what is the expression for the number of cupcakes each daughter gets?
The total number of cupcakes is \(c+c=2c\). When Maggie ate one cupcake there are now \(2c-1\) cupcakes left to divide between the 3 daughters. So each daughter gets \(\boxed{\frac{2c-1}{3}}\) cupcakes.
