DIA [1.3K]

Answer:

35 People

Step-by-step explanation:

From the given information

$125 was charged for the rental of the hall
Each Meal costs $12
Total Bill = $545

Let the number of people attending the banquet=x

Therefore:

Cost of Hall Rental + Total Meal Cost = Total Bill

125+12x=545

12x=545-125

12x=420

x=420/12=35

Since x=35, we conclude that 35 People attended the banquet.
