To calculate the total amount of peanut butter Mrs. Johnson uses each day to make 6 batches of peanut butter fudge, you can multiply the amount of peanut butter used for one batch by the number of batches:
Amount of peanut butter used for one batch = 3/5 cup
Number of batches made each day = 6
Total amount of peanut butter used each day = (3/5 cup/batch) * 6 batches
Now, perform the calculation:
Total amount of peanut butter used each day = (3/5) * 6 = (3/5) * (6/1) = 18/5 cups
So, Mrs. Johnson uses 18/5 cups of peanut butter each day to make 6 batches of peanut butter fudge in her bakery.
