A school is planning an event to raise $1,000 for charity. The cost of organizing the event is $200. The tickets are priced at $
Leviafan [203]
Here is how to solve this question.


Since x represents children and y represents adults.

1,000 = (6x+8y) - 200     

6x + 8y = 1,000 + 200


6x + 8y = 1,200  


1,000 = 8y - 200


1,000 + 200 = 8y


1,200 = 8y


1,200/8 = 8y/8


150 = y

 
150 adults need to attend for the organizers to raise the targeted amount.


Happy studying ^-^
