Question: John and his two brothers decide to split the cost of an apartment. It is 40% more expensive than John's old apartment which costs $1200 per month. How much does John save per year by splitting the apartment compared to living alone?
Answer: His old apartment cost 1200 * 12 = $14,400 per year. His new apartment 1200 * 1.4 = $1680 per month. That means it cost 1680 / 3 = $560 per month. So it cost 560 * 12 = $6720. So he saves 14400 - 6720 = $7680. The answer is 7680.
[Question]Emma bought 3 dozens of macarons in addition to her 10 pieces of macarons for a party. If 15 pieces of macarons are left over, how many pieces of macarons were eaten?
[Answer]Three dozens of macarons are equal to 3 x 12 = 36 pieces of macarons. So Emma has a total of 36 + 10 = 46 pieces of macarons for the party. Therefore, 46 - 15 = 31 pieces of macarons were eaten. The answer is 31.
Q: In the last student council election, the winner got 55% of the votes and the loser got the rest. If the school has 2000 students, but only 25% of them voted, how many more votes did the winner get than the loser?
A: 500 students voted because 2000 x .25 = 500. The loser got 45% of the votes because 100 - 55 = 45. The winner got 275 votes because 500 x .55 = 275. The loser got 225 votes because 500 x .45 = 225. The winner got 50 more votes because 275 - 225 = 50. The answer is 50.
Question: Kwame studied for the history test for 2.5 hours. Connor studied for 1.5 hours and Lexia studied for 97 minutes. How many minutes more did Kwame and Connor study than Lexia?
Answer: Kwame = 2.5 hours * 60 minutes = 150 minutes. Connor = 1.5 hours * 60 minutes = 90 minutes. Kwame + Connor = 150 + 90 = 240 minutes. 240 - 97 = 143 minutes. Kwame and Conner studied 143 minutes more than Lexia. The answer is 143.
[Question]Perry wants to buy a new modern bedroom set for $2000. He received $200.00 in gift cards over the holidays that he can use toward the set. The store is currently offering the entire set at 15% off. If he signs up for the store credit card and uses it to buy the set, he will save an additional 10% off on the discounted set. What is the final price of the set?
[Answer]The bedroom set is $2000 and it’s currently 15% off so 2000 * .15 = $300.00 off. So the new price of the set is 2000 - 300 = $1,700.00. He signs up for the credit card so that’s 10% off so .10 * 1700 = $170.00. Now the set is 1700 - 170 = $1,530.00. He has a $200.00 gift card which brings the price to 1530 - 200 = $1,330.00. The answer is 1330.
[Question]Janet makes 50 snowballs and her brother makes 150 snowballs. What percentage of the snowballs did Janet make?
[Answer]
First add the number of snowballs each person made to find the total: 50 snowballs + 150 snowballs = 200 snowballs. Then divide the number Janet made by the total number and multiply by 100% to express the answer as a percentage: 50 snowballs / 200 snowballs * 100% = 25%. The answer is 25.
