I got corrected by mreijepatmat, and this is what they said: "Let x be this number so (x+5)(x-5) =75 ===> x^2 -25 = 75 ===> x^2 =100 & x = 10."
I hope this answer helped you! If you have any further questions or concerns, feel free to ask! :)

Answer:
y = 6.50x + 6 or 71 = 6.50x + 6
10 people are the max you can invite
Step-by-step explanation:
We have the simple equation
y = 6.50x + 6
6.50x because it it per person
6 because it is a flat one time charge
We want the max to be 71 so that will be our y
71 = 6.50x + 6
We are now going to solve for x
65 = 6.5x
x = 10
Hope it helps! (:
