Answer:
[tex]T_f=9^{\circ} F[/tex]
Step-by-step explanation:
It is given that,
Initial temperature, [tex]T_i=3^{\circ} F[/tex]
The decrease in temperature when she woke up is, [tex]\Delta T=6^{\circ} F[/tex]
We need to find the temperature when Ava woke up.
Change in temperature = final temperature-initial temperature
[tex]6\ ^{\circ}F=T_f-3^{\circ}F\\\\T_f=9^{\circ} F[/tex]
So, when she woke up the temperature was 9°F.
