Ms. Higdon is planning her wedding. One venue charges

Diano4ka-milaya [45]

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 = $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 = $150 per person

So, the charge for m people = m x ($150) = 150 m

So ,The total charge of Venue 2 = 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.
