Final answer:
To determine the number of cups of flour used to make x batches of the Cheezy Peezy recipe, we can use the simplified expression (8 1/2 + 1/2) * x cups.
Step-by-step explanation:
To determine the number of cups of flour used to make x batches of the Cheezy Peezy recipe, we can start with the amount of flour used for one batch by Peppy Pizza, which is 8 1/2 cups. Since Cheezy Peezy uses 1/2 cup flour more per batch than Peppy Pizza, the amount of flour used for one batch by Cheezy Peezy can be expressed as (8 1/2 + 1/2) cups.
To find the total amount of flour used for x batches, we can multiply the amount of flour used for one batch by the number of batches. Therefore, the simplified expression to determine the number of cups of flour used to make x batches of the Cheezy Peezy recipe is (8 1/2 + 1/2) * x cups.
