Final answer:
Ledger should use the algorithm method to double the recipe accurately and efficiently.
Explanation:
When Ledger needs to double a recipe, he can use the algorithm method to solve this problem. Algorithms provide a step-by-step procedure to achieve a specific outcome, in this case, doubling the recipe. This approach ensures accuracy and efficiency in increasing the quantity of ingredients.
By applying an algorithm to double the recipe, Ledger can systematically modify the ingredient quantities while cooking, guaranteeing that he has enough food for all his friends. Using algorithms in cooking mirrors the concept of stoichiometry in chemical reactions, where precise measurements are crucial for the outcome.
