teenagers need at least 1200 mg of calcium a day.
one cup of milk cantains 300 mg of calcium.
one cup of ice cream contains 150 mg of calcium.
suppose a teenager drinks 2 cups of milk a day, how many cups of ice cream could he eat?
:
Let c = cups of ice cream required
:
Milk + ice cream => 1200 mg
300(2) + 150c => 1200
600 + 150c => 1200
Subtract 600 from both sides
150c => 1200 - 600
150c => 600
divide both sides by 150
c =
c => 4 cups of ice cream
:
We can say if he consumes 2 cups of milk, he should have 4 or more cups of ice cream
