Please help with this practice problem I am having difficulty on. I will be sure to leave a review!

The flowchart below shows the process for baking cookies with various mix-ins (e.g. chocolate chip, M&Ms, raisins), and the table gives the time and resources needed in each step. Words 'same kind' mean the batches of cookies have the same mix-in ingredient, so enough dough for up to 3 dozen can be mixed at the same time. The oven is small and only one dozen cookies can be baked at a time.
