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?
To solve this one would use Algebra 1 and set up the inequality by: 1000 < = 299*m + 261*j

Sally's parents tell her she has to pay for her cell phone. Her cell phone costs 10$ per month for data plus .15$ for every minute she is on her phone. How many minutes can sally be on her phone if she can only afford a 25$ bill?
The answer solution can be solved using 25 = 10 + .15*x where x is solved to be 100 minutes.
