Answer:
When the number of guests is 0, the cost would be $450.
Step-by-step explanation:
We have been given an equation [tex]C=450+28g[/tex], which models the relation between the cost in dollars, C, of the banquet and the number of guests, g.
We can see that our given equation in slope-intercept form of equation [tex]y=mx+b[/tex], where, m represents slope of line and b represents y-intercept or initial value.
We can see that slope for our given equation is 28 and the C-intercept is 450.
The C-intercept tells us that when there are 0 guests in the banquet, the cost would be $450.
