If a customer purchases 6 through 10 books, he or she earns 10 points for each book. If a customer purchases 11 or more books, he or she earns points equal to 20 points for each book.

Each card represents a number. An ace, king, queen, and jack represent 1, 13, 12, and 11, respectively. Enter an expression that uses the four numbers from the four selected cards. Each card number can be used only once in each expression, and each card must be used. You can use the operators ( *, and /) and parentheses in the expression. The expression must evaluate to 24. After entering the expression, click the Verify button to check whether the numbers in the expression are currently selected and whether the result of the expression is correct. Display the verification in a dialog box. You can click the Refresh button to get another set of four cards.
