Answer:

the answer is 12 attendees

Step-by-step explanation:

Let a=the attendees & Let d=the cost

if the budget is $97 and the cost of the gala is represented by the equation d=7a+13, substitute the $97 for d

d=7a+13

97=7a+13

now take subtract 13 from both sides

97-13=7a+13-13

since the 13 cancels out on the right side it'll now read:

84=7a

to get a by itself you now divide 7 from both sides getting a by itself

84/7=7a/7

12=a

so the answer will be 12
