After the expiration date, a vitamin's calcium content decreases. If each tablet initially contains 500 mg of calcium, and 325 mg deteriorates, what is the remaining total amount of calcium per tablet?
Correct answer
A
Rationale
To determine the remaining calcium content per tablet, subtract the deteriorated amount from the initial amount: 500 mg - 325 mg = 175 mg. After deterioration, each tablet will have 175 mg of calcium remaining. Therefore, the correct answer is A (175 mg). The calculation involves simple subtraction to find the difference between the initial calcium content and the deteriorated amount, providing the accurate remaining total calcium content per tablet.
