Question

Most sports drinks contain minerals. Research shows that the most effective sports drink has a magnesium to calcium ratio of 1: 2. The body absorbs about 87% of magnesium in a drink, and about 44% of calcium in a drink.

One serving of a particular sports drink contains
about 96 mg of calcium and 48 mg of magnesium. About how many milligrams of each mineral will the body absorb?

Answer 1

41 mg magnesium

42 mg calcium

Explanation:

87% of magnesium; 48 mg of magnesium

44% of calcium; 96 mg of calcium

87% × 48 mg magnesium = 0.87 × 48 mg magnesium = 41 mg magnesium

44% × 96 mg calcium = 0.44 × 96 mg calcium = 42 mg calcium
