The FDA's acceptable daily intake for Allura Red Dye is 7.0 mg/kg bodyweight per day Calculate how many servings a 200-lb person may have per day (or if you would like to, calculate how many servings you may have per day). In 1 kg, there are 2.20 lbs
How many servings can a 5-year-old child, weighing 55-lb, drink in a day to remain below an acceptable daily intake of 7.0 mg/kg bodyweight?

Explanation:

1. The Food

You need to assume the content of Allura Red Dye in the food or beverage that will be consumed.

Assume that it is a beverage and that it contains 50 mg of Allura Red Dye per liter.

Also, you need to assume the size of a serving. Assume it is 250 ml.

Then, one serving contains: 50mg/1liter × 250ml × 1liter/1,000ml = 12.5mg

1. Calculate how many servings a 200-lb person may have per day.

i) Acceptable daily intake: 7.0mg/kg (given)

ii) 200 lb (given)

iii) Convert to kg: 200 lb × 1 kg /2.20lbs = 90.90 kg

iv) Set a proportion:

v) Solve for x:

vI) Calculate the number of servings:
