Concept explainers
Medical Staff People who work in the medical field need to be careful when prescribing medicine or advising patients about medications. One way that the approximate number of milligrams m of a medicine that should be given to a child of age c when the usual adult dosage is x milligrams can be calculated by using the following equation. Use the equation to solve exercises 35 and 36. Round your answers to the nearest whole number.
Find the amount of ibuprofen to give a child of age 10 if the usual adult dosage is 325 milligrams.
