Two formulas that approximate the dosage of a drug prescribed for children are: Young's Rule: C = 
and Cowling's Rule: C = 
.In each formula, A = the child's age in years, D = an adult dosage, and C = the proper child's dosage. The formulas apply for ages 2 through 13. Use these formulas to solve the problem.Use Cowling's Rule to find the difference in a child's dosage for a 10-year-old child and a 6-year old child.
