Question 282341
cost of the plane is $200,000


There are x number of people in the group.


If the group adds 5 people, there will be x+5 people in the group and the cost per person will be $2,000


The cost per person would be the total cost divided by the number of people in the group.


Your equation would be:


$200,000/(x+5) = $2,000


Multiply both sides of this equaqtion by (x+5) to get:


$200,000 = $2,000 * (x+5)


Divide both sides of this equation by $2,000 to get:


100 = x + 5


Subtract 5 from each side of this equation to get:


x = 95


There are 95 people originally in this group.


They add 5 and the number of people in the group becomes 100.


$200,000 / 100 = $2,000 per person.
