Final Answer:
The most caffeine that can be in a 12-oz serving of soda pop according to regulations is 71 mg. Thus option c is correct.
Step-by-step explanation:
According to the U.S. Food and Drug Administration (FDA), the limit for caffeine in soda pop is set at 0.02% by weight. Considering a 12-oz serving size, we can calculate the maximum allowable caffeine content as follows:
Firstly, convert the percentage to milligrams: 0.02% of 12 oz = (0.02/100) * 12 * 28.35 g/oz = 6.8124 mg. This result represents the maximum allowable caffeine content per 12 oz.
However, the FDA allows a tolerance of 20% above the declared value. Therefore, to find the upper limit, we perform: 6.8124 mg + (20/100 * 6.8124 mg) = 6.8124 mg + 1.36248 mg = 8.17488 mg.
Therefore, the maximum allowable caffeine content, accounting for the 20% tolerance, is approximately 8.175 mg. Rounding this value, it remains under 71 mg.
Thus, in compliance with FDA regulations, the maximum amount of caffeine that can be present in a 12-oz serving of soda pop stands at 71 mg, ensuring consumer safety and adherence to regulatory standards.
Thus option c is correct.
