Costa is planning a lunch banquet. the equation c=450+28g models the relation between the cost in dollars, c, of the banquet and the number of guests, g. interpret the c-intercept of the equation.

When the number of guests is 0, the cost would be $450.

Step-by-step explanation:

We have been given an equation , 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 , 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.

a. she will receive a refund of $278.
