Answer:
9
Step-by-step explanation:
If n is the number of people attending, we want the amount paid by each to add up to the total bill. That is ...
n × 12.62 = 113.58
This is solved by dividing both sides of the equation by 12.62, the coefficient of n. Doing that will make the coefficient n become 12.62/12.62 = 1.
113.58/12.62 = n = 9
