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.
[Question]The number of dishes Sandrine washed was 10 more than the number of bananas Charles cooked. Also, the number of bananas Charles cooked was 3 times the number of pears he picked. If Charles picked 50 pears, how many dishes did Sandrine wash?
[Answer]If the bananas Charles cooked were 3 times the number of pears he picked, then Charles cooked 3 * 50 = 150 bananas. Since all the dishes that Sandrine washed were 10 more than the number of bananas Charles cooked, Sandrine washed 150 + 10 = 160 dishes. The answer is 160.
Q: Julie, Letitia and Anton decided to have dinner together at a nearby restaurant. Julie orders $10 worth of food, Letitia orders $20 worth of food, and Anton orders $30 worth of food. How much should each pay in tips if they want to split a 20% tip for the whole meal evenly?
A: First, we need to determine how much the entire meal costs before we can determine the tip. We perform 10 + 20 + 30 = 60 dollars worth of food. Now we need to find out how much the total tip to be paid is, by multiplying 60 * .2 = 12 dollars in tips. Since they want to split this evenly amongst three people, this works out to 12 / 3 = 4 dollars in tips per person. The answer is 4.
Question: Jeff orders a Halloween costume. He has to put in a 10% deposit and then pay the rest when he picks it up. The costume is 40% more expensive than last year's costume, which cost $250. How much did he pay when picking it up, in dollars?
Answer: It cost 250 * .4 = $100 more than his old costume. So it cost 250 + 100 = $350. He left a 350 * .1 = $35 deposit. So he had to pay 350 - 35 = $315. The answer is 315.
[Question]James sells a $500,000 house for 20% over market value. He splits the revenue with his 3 brothers. How much does each person get after taxes take away 10%?
[Answer]He sells the house for 1 + .2 = 1.2 times its value. So he sells the house for 500,000 * 1.2 = 600,000. He splits the money 1 + 3 = 4 ways. So each person gets 600,000 / 4 = $150,000 before taxes. Taxes take away 150,000 * .1 = $15,000. So each person gets 150,000 - 15,000 = $135,000. The answer is 135000.
[Question]Lily types 15 words a minute and takes a 2-minute break every 10 minutes. How long does it take for Lily to type 255 words?
[Answer]
It would take Lily 255 words / 15 wpm = 17 minutes to type without taking a break. Since Lily takes a break after 10 minutes of typing she takes 17 minutes + 2 minutes = 19 minutes. The answer is 19.
