The charity gala will cost $270 if it has 15 attendees. How many attendees can there be, at most, if the budget for the charity gala is $558? Assume the relationship is directly proportional.

31

Step-by-step explanation:

 For 15 people the charity gala costs $270, so for 1 person it costs 270÷15 = 18.So, $18 for each person, now you have a budget of $558, therefore you divide 558 by 18 = 31This concludes that the total number of attendees that can be at the gala is 31.
