Type 1 rice:

7-ounce package costs = 2.59.

Cost of 1-ounce of Type 1 rice = 2.59/7 = $0.37

Type 2 rice:

12-ounce package costs = $4.56

Cost of 1-ounce Type 2 rice = 4.56/12 = $0.38

Type 3 rice:

18-ounce package costs = $ 6.30

Cost of 1-ounce Type 3 rice = 6.30/18 = $0.35.

From the above calculations, we can see that the cost of 1-ounce Type 3 rice is lowest. Therefore, 18-ounce package is Best Buy.
