The variable is percent of body weight carried in the school backpack. So a child who weighs $60$ pounds and carries $9$ pounds has a variable value of $15\%(9-$: $60=0\mathrm{.}15=15\%).$ The American Chiropractic Association $($ACA$)$ recommends that children carry no more than $10\%$ of their body weight.
