We can write an equation for each company where y is the total charge and x is the number of people so:
Equation 1 (A+ food):
[tex]y=35x+75[/tex]Equaton 2 (Super Carter):
[tex]y=38x[/tex]b) if she expects 28 guests we can replace that in bout equation and see which one is cheaper.
Equation 1:
[tex]\begin{gathered} y=35(28)+75 \\ y=1055 \end{gathered}[/tex]Equation 2:
[tex]\begin{gathered} y=38(28) \\ y=1064 \end{gathered}[/tex]So option 1 is the best option.
