After practice, Dylan drank = 12.9 ounces
Remaining amount of water = Total quantity of water in the container - Amount of water is drunk before practice - Amount of water is drunk before practice
[tex]x=28-5.2-12.9\\ \\ x=28-18.1\\ \\ x=9.9\ ounces[/tex]
Thus, 9.9 ounces of water remaining in the container.
