  1. Calculate Calcium Amounts: Calculate the amount of calcium in one cup of milk and one cup of juice.
  2. Set Up Inequality: Set up the inequality to represent the total daily calcium intake from milk and juice.
  3. Compare to Recommended Intake: Compare the total calcium intake to the recommended daily intake.
