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?

Rationale

Each tablet retains 175 mg of calcium after deterioration.

Initially, each tablet contains 500 mg of calcium. If 325 mg deteriorates, subtracting this amount from the initial content leaves 175 mg of calcium remaining in each tablet.

A (175 mg) CORRECT

This choice is calculated by taking the initial calcium content of 500 mg and subtracting the 325 mg that deteriorates. The calculation (500 mg - 325 mg) results in 175 mg, correctly representing the remaining calcium per tablet.

B (185 mg) YOUR ANSWER

Choosing 185 mg suggests an incorrect calculation of the calcium remaining after deterioration. This would imply that only 315 mg has deteriorated (500 mg - 185 mg), which does not align with the provided data that specifies 325 mg has deteriorated.

C (135 mg) YOUR ANSWER

Selecting 135 mg indicates a misunderstanding of the deterioration process. If we were to arrive at 135 mg, this would mean that 365 mg has deteriorated (500 mg - 135 mg), which exceeds the stated deterioration of 325 mg and is therefore incorrect.

D (200 mg) YOUR ANSWER

Opting for 200 mg implies that only 300 mg has deteriorated (500 mg - 200 mg), which again does not match the given deterioration of 325 mg. This indicates a failure to accurately apply the deterioration figure in the calculation.

Conclusion

The correct amount of calcium remaining per tablet after the specified deterioration is 175 mg. This conclusion is derived directly from subtracting the amount that deteriorates from the initial calcium content, leading to a clear understanding of the remaining nutrient level in the vitamin tablets. Choices that suggest different amounts indicate errors in the applied calculations based on the deterioration data provided.

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?

Each tablet retains 175 mg of calcium after deterioration.
