Problema Solution
Roberta is prescribed 8 milligrams of medication everyday, based on her weight of 140 pounds. Three months later, she weighs 120 pounds. Assuming the dosage is based on weight, what should the new dosage be?
Answer provided by our tutors
dosage = k * weight
where k is any constant.
When weight = 140 pound then dose = 8 miligram
=> 8 = k * 140
=> k = 8/140
so, when weight = 120 pound
then dose = 8/140 *120 = 6.857 miligram( rounded off to three decimal places).
