Write an Inequality to Represent the Situation

The recommended daily calcium intake for a 20-year-old is 1,000 milligrams (mg). One cup of milk contains 299 mg of calcium and one cup of juice contains 261 mg of calcium. Which of the following inequalities represents the possible number of cups of milk m and cups of juice j a 20-year-old could drink in a day to meet or exceed the recommended daily calcium intake from these drinks alone?
​A.)  299m + 261j ≥ 1,000

B.)  299m + 261j > 1,000

C.)  299      261
      ------ + ------ ≥ 1,000
        m          j

​D.)  299      261
      ------ + ------ > 1,000
        m          j

---

m = number of cups of milk
j = number of cups of juice

One cup of milk contains 299 mg of calcium
One cup of juice contains 261 mg of calcium

Write an inequality that represents meeting or exceeding the recommended 1,000 mg of daily calcium intake.

299m + 261j ≥ 1,000   {the ≥ sign shows that it may meet or exceed 1,000 mg}

​A.)  299m + 261j ≥ 1,000
