A restaurant charges $100 to rent its banquet room for an event. It also charges $15 to serve dinner to each guest. Write an equation for the total cost (t) of renting the banquet room in terms of the number of guests (g). How many guests attend if the total cost of an event is $2200?

t = 100 + 15x

= 140 guests

Step-by-step explanation:

Rent for banquet room = $100

Dinner per guest = $15

Let

x = number of guests

Total cost = Rent for banquet room + (Dinner per guest * number of guests

Total cost, t = 100 + 15x

How many guests attend if the total cost of an event is $2200?

t = 100 + 15x

2,200 = 100 + 15x

2200 - 100 = 15x

2,100 = 15x

x = 2,100/15

x = 140 guests

x = number of guests = 140 guests

it is b)

hope this : )

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
