Answer 1

Answer:

150 adults would have to attend the event, for the organizers to raise the targeted amount.

Step-by-step explanation:

Given is:

A school is planning an event to raise $1,000 for charity.

The cost of organizing the event is $200.  

The ticket prices are: $6 per child and $8 per adult.

Let x represents children and y represents adults.

The equation that represents the total revenue is:

$1000=6x+8y-200$    

$6x+8y=1000+200$

=> $6x+8y=1200$

If the event was only for adults:

$1000=8y-200$

$1000+200=8y$

$8y=1200$

y=150

Therefore, 150 adults would have to attend the event, for the organizers to raise the targeted amount.

Answer 2

6c + 8a - 200 = 1000 ....or could be 6c + 8a = 1200

if no kids came...only adults..
6(0) + 8a = 1200
8a = 1200/8
a = 150 <== 150 adults would have to attend
