My question is: Six kids and two adults are going to the circus. Kid's tickets are on sale for only half of the adult tickets. The total cost is $50. How much is one kid's ticket? Your thoughts:
Let X be the price of one kid's ticket. So the price of one adult ticket is X * 2. Five kids and two adults are going to the circus, so 6 * X + 2 * (X * 2) = $50. So 10X = $50. So the price of one kid's ticket is X = $5. The final answer: 5.
