Question

an adult ticket to a museum costs 3 dollars more than a childs ticket. when 200 adult tickets and 100 childrens tickets are sold, the total revenue is 2100 dollars. What is the cost of a childs ticket and please explain

Answer 1

x=child's ticket price

`200(x+3)+100x=2100\\200x+600+100x=2100\\300x+600=2100\\300x=1500\\x=5`

So adult's ticket price would be:

`x+3`

`5+3=8`
