The cost to cater a wedding has two components. The first is the fixed cost of $939, which is charged regardless of the number of people served a meal. The second component is the cost per person served, which is $8. Therefore, the linear model that relates the cost to the number of people served a meal is given by:

C = 939 + 8x

where x is the number of people served a meal.

A Caterer Charges $939 to Cater a Wedding Plus $8 C=947xC = 947 xC=947x

A Caterer Charges $939 to Cater a Wedding Plus $8 $C = 947 x$
