Answer: \(5^{\circ}\ F\)
Step-by-step explanation:
Given: When you woke, the temperature was = \(15^{\circ}\ F\)
Since, the temperature went down \(2^{\circ}\ F\) each hour.
Therefore, the total temperature went down after 5 hours will be :-
\(5\times2^{\circ}\ F=10^{\circ}\ F\)
Thus, the final temperature will be :-
\(15^{\circ}\ F-10^{\circ}\ F=5^{\circ}\ F\)
Hence, the final temperature will be \(5^{\circ}\ F\).
