Q: Lucille is wondering who has the tallest house between her and her neighbors. His family's house is 80 feet tall. One neighbor's house is 70 feet tall. Another neighbor's house is 99 feet tall. How much shorter is Lucille's house than the average height?
A: The houses are 249 feet in total because 70 + 80 + 99 = 249. The average height is 83 feet because 249 / 3 = 83. Her house is 3 feet shorter because 83 - 80 = 3. The answer is 3.
Question: Tommy wants to earn enough money to buy 8 new books. Each book costs $5. If Tommy already has $13, how much does he need to save up?

Q: Carson is covering the high school football field with grass seed. Each square meter needs three times as much seed as fertilizer. If Carson uses 60 gallons of seed and fertilizer combined, how many gallons of seed does he use?
A: Let s be the number of gallons of seed Carson uses and f be the number of gallons of fertilizer. We know that s = 3f and s + f = 60. Substituting the first equation into the second equation produces 3f + f = 60. Combining like terms, we get 4f = 60. Dividing both sides by 4, we get f = 15. Substituting that value into the equation s = 3f, we get s = 3 * 15 = 45. The answer is 45.
Question: Anderson makes mud masks for spa treatments. In every batch of mud that he mixes, he adds three sprigs of mint, and he adds two green tea leaves for every sprig of mint. He had to switch to a different kind of mud, which makes the other ingredients he adds half as effective. How many green tea leaves should Anderson add to a new batch of mud to get the same efficacy as before?
Answer: Anderson adds 3 * 2 = 6 green tea leaves in every batch of mud. They are half as effective in the new mud, so Anderson should ad 6 * 2 = 12 green tea leaves to get the same efficacy as before. The answer is 12.
Q: A family is going to the amusement park. The adult tickets cost $22 for admission, and the tickets for children cost $7. The family consists of 2 adults and 2 children. What is the total price the family will pay for admission?
A:
To solve this problem you can set up an equation to represent the total price the family will pay, with a representing the number of adult tickets, c representing the number of children’s tickets, and p representing the total price of admission. Thus 22a + 7c = p. Plug in the number of adults and children that plan to go to the amusement park: 22(2) + 7(2) = $58 is the total cost for admission. The answer is 58.
