Final answer:
By taking 4 tablets a day, each containing 500mg of calcium carbonate, a person receives 2000 mg of calcium carbonate per day.
Step-by-step explanation:
If a person takes 4 tablets a day and each tablet contains 500mg of calcium carbonate, then the total amount of calcium carbonate they would consume in a day is calculated by multiplying the amount of calcium carbonate per tablet by the number of tablets taken daily.
To find out how many milligrams of calcium are obtained:
- First, we consider the amount of calcium carbonate per tablet, which is 500 mg.
- Next, we multiply this amount by the number of tablets taken per day: 500 mg/tablet × 4 tablets/day = 2000 mg/day.
Therefore, the person obtains 2000 mg of calcium carbonate per day by taking 4 tablets.
