Question: 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?
Answer: 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 answer is 5.

Question: Wallace's water heater is twice the size of Catherine's water heater. If the capacity of Wallace's water heater is 40 gallons and it's 3/4 full, calculate the total number of gallons of water they both have if Catherine's water heater is also full with water to 3/4 of its capacity.
Answer: When 3 / 4 full of water, Wallace's water heater has 3 / 4 * 40 = 30 gallons of water. Catherine's water heater capacity is 40 / 2 = 20 gallons. When 3 / 4 full, Catherine's water heater has 3 / 4 * 20 = 15 gallons of water. Together, when 3 / 4 full with water, Wallace's and Catherine's water heaters hold 15 + 30 = 45 gallons of water. The answer is 45.

Question: Jermaine, Terrence, and Emilee earn a total of $90. Jermaine earns $5 more than Terrence in a month. If Terrence earns $30, how much does Emilee earn?
Answer: If Terrence earns 30 dollars, then Jermaine earns $30 + $5 = $35 dollars. The total earnings of the two are $30 + $35 = $65 dollars. Emilee earns $90 - $65 = $25 dollars. The answer is 25.

Question: Mark got a 5% raise at his job. Before the raise, he earned 40 dollars per hour. He works 8 hours per day for 5 days per week. His old bills used to be 600 dollars a week but he decided to add a hundred dollar a week personal trainer. How much does he have leftover a week?
Answer:
After the raise he earns 40 * 1.05 = 42 dollars an hour. He works 8 hours per day so earns 42 * 8 = 336 per day. He works 5 days per week so he earns 336 * 5 = 1680 a week. His expenses after adding the personal trainer are 600 + 100 = 700 a week. So he has 1680 - 700 = 980 left over. The answer is 980.
