Answer:
80 people would need  to attend for the venues to cost the same amount.
Step-by-step explanation:
Let the total number of people who attend the wedding  = m
The venue charges of venue 1 = $10,000
The per person charge of Venue 1 Â = $25 per person
So, the charge for m people  =  m x ($25)  = 25 m
So ,The total charge of Venue 1 = Venue Charge  +  People Cost
= $10, 000 + 25 m
Now, The per person charge of Venue 2 Â = $150 per person
So, the charge for m people  =  m x ($150)  = 150 m
So ,The total charge of Venue 2 = Â 150 m
According to question:
For m people both charges are equal  ⇒ $10, 000 + 25 m  = 150 m
or, 10,000 = 150 m - 25 m
⇒ 125  m  = 10,000
⇒ m  = 10,000 / 125 = 80
or, m  = 80
Hence,  80 people would need  to attend for the venues to cost the same amount.
