Explanation:

1.

Step1: Convert ounces to pounds

Since 1 pound = 16 ounces, 8 ounces = $\frac{8}{16}=0.5$ pounds.

Step2: Calculate tare - weight

Tare - weight = gross - weight - weight of empty case. Gross weight is 8.75 pounds and weight of empty case is 0.5 pounds. So tare - weight = 8.75 - 0.5 = 8.25 pounds.

When fruits are cut and exposed to air, the oxygen in the air reacts with certain substances in the fruit, which is an oxidation reaction.

Step1: Convert pounds to ounces

Since 1 pound = 16 ounces, a 5 - pound case of green beans has 5×16 = 80 ounces.

Step2: Calculate remaining ounces

After discarding 4 ounces, the remaining weight is 80 - 4=76 ounces.

Step3: Calculate number of portions

If the portion size is 2 ounces, then the number of portions is $\frac{76}{2}=38$.
