Q: 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?
A: 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.

Answer: There are 3 groups * 25 people / group = 75 people in total. There are 14 girls + 11 boys = 25 children in total. There are 75 people - 25 children = 50 parents. The answer is 50.
[Question]In Mary's class, there are 25 students. Their teacher told them they could pay $50 each to finance a big science project that they and their society would benefit greatly from. They all paid the full amount except for 4 students, who paid half. How much was the class able to gather together?
[Answer]The original amount is $50 so half is $50 / 2 = $25. 4 students paid half ($25) for a total of 4 * $25 = $100. There are 25 - 4 = 21 students left. 21 students paid the full amount ($50) for a total of 21 * $50 = $1050. They were able to gather a total of $100 + $1050 = $1150. The answer is 1150.
Q: Carl is hosting an open house for his new business. He knows 50 people will show up and hopes that another 40 people will randomly show up. He’s created 10 extravagant gift bags for the first 10 people who visit his shop. He’s made average gift bags for 20 people but needs to make enough for everyone who visits to have one. How many more bags does he need to make?
A: He knows 50 people are showing up and he’s hoping 40 more people will drop in for a total of 50 + 40 = 90 people. He’s made 10 extravagant gift bags and 20 average bags for a total of 10 + 20 = 30 bags. He hopes 90 people will show up and has already made 30 bags so he needs to make 90 - 30 = 60 more gift bags. The answer is 60.

He is open 16 * 5 = 80 hours a week. So he pays each of his employees 12.5 * 80 = $1000 per week. Since there are two employees, he pays them in total 2 * $1000 = $2000 per week. The utilities cost 1200 * .2 = $240. So his total cost per week is 1200 + 2000 + 240 = $3440. The answer is 3440.
