Answer:
x + y = 200
5x + 2y = 610
There were 130 child tickets sold and 70 adult tickets sold
Step-by-step explanation:
**The selection of solutions is not clear from your question so I have written equations and solved them**
Let x = number of adult tickets sold
Let y = number of child tickets sold
If 200 tickets are sold, then x + y = 200
If the total collected was $610, then 5x + 2y = 610
To solve this, rewrite x + y = 200 making x the subject:
x = 200 - y
Substitute x = 200 - y into 5x + 2y = 610 and solve for y:
5(200 - y) + 2y = 610
⇒ 1000 - 5y + 2y = 610
⇒ 1000 - 3y = 610
⇒ 1000 - 610 = 3y
⇒ 390 = 3y
⇒ y = 390 ÷ 3 = 130
Now substitute y = 130 into x + y = 200 to find x:
x + 130 = 200
⇒ x = 200 - 130 = 70
Therefore, there were 130 child tickets sold and 70 adult tickets sold.
Answer:
x + y = 200. 5 x + 2 y = 610. or a
