## Elementary Algebra

A gallon of milk costs 4.16 dollars. First, we need to convert this price from dollars per gallon to dollars per pint.To do this, we multiply $\frac{4.16\ dollars}{1\ gallon}$ by the ratio that converts gallons to pints. The ratio that converts gallons to pints is $\frac{1\ gallon}{8\ pints}$. So, $\frac{4.16\ dollars}{1\ gallon}$ $\times$ $\frac{1\ gallon}{8\ pints}$ = $\frac{4.16\ dollars}{8\ pints}$. $\frac{4.16\ dollars}{8}$ = 0.52 dollars per pint. The price for a pint of milk is 0.52 dollars.
