Functions
Let's use the following variables:
x = number of guests
y = number of order of appetizers provided for them
We know the function represents a ratio, thus:
y = kx
We need to determine the value of k. We know that, for x=8 guests, y=2 appetizers are provided, thus:
2 = k (8)
Dividing by 8:
k = 2/8 = 1/4
Now the function is:
y = 1/4x
[tex]y\text{=}\frac{1}{4}x[/tex]Second choice
