Q: Roe saved $10 per month from January to July and saved $15 per month from August to November. How much should she save in December so she will have a total savings of $150 in the year?
A: Since there are 7 months from January to July, then Roe's savings for those months sum up to $10 x 7 = $70. Since there are 4 months from August to November, then her savings for those months sum up to $15 x 4 = $60. Her total savings from January to November is $70 + $60 = $130. Therefore, she needs to save $150 - $130 = $20 in December. The answer is 20.
Question: A couple with two children, ages 6 and 10 years old, decided to go to an amusement park. The regular ticket costs $109, but children below 12 years old have a $5 discount. If they gave the cashier $500, how much change will they receive?
Answer: The ticket costs 109 - 5 = $104 for each child. So the ticket cost of the two children is 104 x 2 = $208. The couple needs to pay the regular price, so it's 109 x 2 = $218. Thus, the family needs to pay a total of 208 + 218 = $426. Therefore, their change is 500 - 426 = $74. The answer is 74.
[Question]Chad sandwiches 2 crackers with a scoop of peanut butter. He has 5 of these crackers a night before bed. A box of crackers has 4 sleeves with each sleeve holding 28 crackers. How many nights will 5 boxes of crackers last him?
[Answer]Chad uses 2 crackers for each "sandwich" and has 5 sandwiches a night so he eats 2 * 5 = 10 crackers a night. The box has 4 sleeves of crackers and each sleeve has 28 crackers for a total of 4 * 28 = 112 crackers. 1 box has 112 crackers so 5 boxes will have 112 * 5 = 560 crackers. He eats 10 crackers a night and 5 boxes have 560 crackers so they will last him 560 / / 10 = 56 nights. The answer is 56.
Q: Troy's home is 75 meters away from school while Emily's home is 98 meters away from school. Troy and Emily walk to school and back home every day. How much farther does Emily walk to school and back in five days?
A: Troy walks to school and back home for a total of 75 x 2 = 150 meters every day. Emily walks to school and back home for a total of 98 x 2 = 196 meters every day. So Emily walks 196 - 150 = 46 meters farther than Troy every day. In five days, Emily walks 46 x 5 = 230 meters farther. The answer is 230.
Question: Jeff wanted to rent an apartment to live in for the next 5 years until he finishes his studies. He found a nice apartment next to his school, the owner asks Jeff to pay $300 each month, Jeff agreed, and for the first 3 years everything went fine, but then the owner wanted to raise the price for each month to $350. Jeff agreed again and continued paying until he graduated. How much did Jeff end up paying for the apartment throughout the 5 years?
Answer: At first Jeff paid, $300 / month x 12 months = $3,600 / year. He paid $3,600 / year x 3 years = $10,800 the firsts 3 years. The final 2 years he paid $350 / month x 12 months = $4,200 / year. He paid $4,200 / year x 2 years = $8,400 the last 2 years. He paid the owner $10,800 + $8,400 = $19,200 in total. The answer is 19200.
