document.write( "Question 844148: doctors often prescribe the same drugs for children as they do for adults. if \"a\" the age of a child and D is the adult dosage, then to find the child's dosage \"d\", doctors can use the formula d=0.08aD(Fried rule) or d=D(a+1)/24(cowling's rule). For what age do the two formulas give the same child's dosage. \n" ); document.write( "

$\"d=0.08aD\"$ (Fried rule) or $\"d=D%28a%2B1%29%2F24\"$ (cowling's rule).
