Answer:
The answer is Option A
Explanation:
Cup of milk m = 299 mg
Cup of juice j = 261 mg
Limit of intake = 1000mg
Total amount of calcium from milk = 299 × m = 299m mg
Total amount of calcium from juice = 261 × j = 261j mg
Since it must be equal to or exceeding the daily limit u use the GREATER THAN OR EQUAL TO SIGN.
299m + 261j <u>></u> 1000
