66. Young's rule for determining the amount of a medicine dosage for a child is given by
C = where a is the child's age and ad is the usual adult dosage, in milligrams
The dosage of a medication for a 5 year old child must stay between 50mg and 100 mg. Find the equivalent adult dosage.
A= 5
So the adult dosage is between 170 mg and 340 mg.
52. 2|2x - 7| + 11 = 25
When , , the equation can be simplified as
When , the equation is
So the solution is x = 0 or x = 7.
