    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.
