Answer:
For this case, the first thing we are going to do is write the equation that represents this problem.
We then have to define variables:
x: number of guests
y: total cost
The equation modeling the problem is given by:
We observe that the equation is linear.
The appropriate scales for the problem are:
Horizontal axis: 1 in 1 starting from 0.
Vertical axis: $ 20 in $ 20 starting from 0.
