Answer:
She buys 24 pints of milk
Step-by-step explanation:
The conversion rule for a pint to the gallon is represented:
[tex]\text{ 1 pint=0.125 gallons}[/tex]Then, we can make a proportional relationship to determine how many pints of milk she buys:
[tex]\begin{gathered} \frac{1}{0.125}=\frac{x}{3} \\ x=\frac{3}{0.125} \\ x=24\text{ pints} \end{gathered}[/tex]
