Part 1
we have the formula
[tex]F=\frac{9}{5}C+32[/tex]
so
Poconos NY C=15 degrees
substitute in the formula
[tex]\begin{gathered} F=\frac{9}{5}(15)+32 \\ F=27+32 \\ F=59^o \end{gathered}[/tex]
Canada, C=5
substitute
[tex]\begin{gathered} F=\frac{9}{5}(5)+32 \\ F=9+32 \\ F=41^o \end{gathered}[/tex]
Part II
Holiday Inn ------> 80n+10
Days Inn ------> 110n-50
Part III
For n=3
substitute in each expression
Holiday Inn -----> 80(3)+10=$250
Days Inn ------> 110(3)-50=$280
therefore
The cheaper hotel is Holiday Inn
Part IV
Holiday Inn -----> cheaper hotel
Canada ----> the temperature is less than NY
therefore
Erik should go to Canada, to the Holiday Inn
