[Question]A new condo development has 23 floors. Regular floors have 12 units, whereas penthouse floors have only 2 units. If the top 2 floors are assigned for penthouse units, how many units does this condo have in total?
[Answer]If the condo has 23 floors and the top 2 floors are reserved for penthouse then there are 23 - 2 = 21 floors for regular units. If a regular floor has 12 units each, then 21 regular floors would have 12 * 21 = 252 units. If a penthouse floor has 2 units each, then 2 penthouse floors would have 2 * 2 = 4 units. The total units in the property would then be 252 regular + 4 penthouse or 252 + 4 = 256 units. The answer is 256.
Q: Diana is twice as old as Grace is today. If Grace turned 3 a year ago, how old is Diana today?

Question: At Peanut Emporium, peanuts cost $3 per pound with a 15-pound minimum. If Baxter spent $105 on peanuts, how many pounds over the minimum did he purchase?
Answer: Start by figuring the number of pounds Baxter bought. $105 / $3 per pound = 35 pounds of peanuts. 35 pounds bought - 15 pounds minimum = 20 pounds over. The answer is 20.
[Question]Twice the money Jericho has is 60. He owes Annika $14 and also owes half as much to Manny. After paying off all his debts, how much money will Jericho be left with?
[Answer]Jericho has $60 / 2 = $30. He owed Manny $14 / 2 = $7. His debts amount to $14 + $7 = $21. So Manny will have $30 - $21 = $9 left. The answer is 9.
Q: Quinten sees three buildings downtown and decides to estimate their heights. He knows from a book on local buildings that the one in the middle is 100 feet tall. The one on the left looks like it is 80% of the height of the middle one. The one on the right looks 20 feet shorter than if the building on the left and middle were stacked on top of each other. How tall does Quinten estimate their total height to be?
A: He estimates the building on the left is 80 feet tall because 100 x .8 = 80. The combined height of the left and middle is 180 because 100 + 80 = 180. The building on the right he estimates as 160 feet because 180 - 20 = 160. He estimates the combined height as 340 feet because 80 + 100 + 160 = 340. The answer is 340.
Question: Jesse and Mia are competing in a week long race. They have one week to run 30 miles. On the first three days Jesse averages (2/3) of a mile. On day four she runs 10 miles. Mia averages 3 miles a day over the first 4 days. What is the average of their average that they have to run over the final three days?
Answer:
Jesse runs 2 miles in the first three days because 3 x (2 / 3) = 2. Jesse has 18 miles left to run because 30 - 10 - 2 = 18. Jesse has to run an average of 6 miles a day because 18 / 3 = 6. Mia runs 12 miles over the first four days because 4 x 3 = 12. She has 18 miles left to run because 30 - 12 = 18. She has to run six miles a day because 18 / 3 = 6. The total they both have to run is 12 miles a day. The average they have to run per day on average is 6 miles because 12 / 2 = 6. The answer is 6.
