Answer:
t = 100 + 15x
= 140 guests
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
