 a can of lemonade comes with a measuring scoop and directions for mixing are 2 scoops of mix for every 38 cups of water. how much water is needed to make the entire can of lemonade if there are 40 scoops of mix?

there are 3.8 milligrams of iron in a 3.5 ounce serving of beef. how much iron is in 8 ounces of beef ? round to the nearest tenth of a milligram.

x/ 8 oz = 3.8 mg/3.5 oz

x = 8(3.8/3.5) = 8.9 mg of iron
