Number of teammates
ExplanationStep 1
set the equation:
a) let H represents the number of hot dogs
let G represents the number of guest
hence, as the number of hotdgos depends on the number of guests then the the independent variable is the nuber of guest
so
Independent variable: number of guests
b)The coach wants to have two hot dogs for each guest, and 8 extra hot dogs in case some teammates bring friends,so
[tex]\begin{gathered} hot\text{ dogs= 2 per guest + 8} \\ H=2G+8 \end{gathered}[/tex]so, the equation is
[tex]H=2G+8[/tex]and the independent variable is
Number of teammates
