Section12.10Unit 1a Subgoal Labeled Puzzles for Toggle Code
These are copies of the Mixed Up Code Practice 1a puzzles with subgoal labels added. The Unit 1a Toggle Code Practice page uses them as the Get Help puzzles for its write code problems. Problems whose solution has fewer than two subgoals keep the original, unlabeled puzzle.
The following program segment should figure out the cost for each shirt if they are buy 2 and get the third free and they are originally $45 each. But, the blocks have been mixed up. Drag the blocks from the left and put them in the correct order on the right. Click the Check button to check your solution.

double totalCost = price * 3; #paired
---
// Split the total paid equally among the shirts
double pricePerShirt = totalCost / 3;
