The Federal Drug Administration (FDA) recommends that the average person consumes no more than 1300 milligrams, mg of calcium each day. Given 1000 mg = 1 g, if a person has already consumed 0.5 g of calcium in a day, what is the maximum number of mg of calcium they can still consume in that same day?

Question

B Rationale: A person who has already consumed 0.5 g of calcium can still consume a maximum of 800 mg of calcium that day, based on the FDA's recommendation of no more than 1300 mg daily.

Since 0.5 g equals 500 mg, subtracting this from the recommended daily limit of 1300 mg leaves 800 mg available for further consumption. The other options do not meet this requirement; 12.5 mg and 10.8 mg are far too low to utilize the remaining allowance, while 1299.5 mg exceeds the limit by 499.5 mg, which is not permissible. Thus, the only viable amount that adheres to the FDA's guideline is 800 mg.
