The charity gala will cost $780 if it has 60 attendees. How many attendees can there be, at most, if the budget for the charity gala is $1,131? Assume the relationship is directly proportional.

attendees

Let x be the maximum number of attendees.

We know that the cost of the charity gala and the number of attendees are directly proportional, so we can set up the following proportion:

780/60 = 1131/x

Cross-multiplying, we get:
780 * x = 60 * 1131

Simplifying, we get:
780x = 67860

Dividing both sides by 780, we get:
x = 67860 / 780 = 87

Therefore, the maximum number of attendees for the charity gala is 87.
