[Question]Thomas wants to throw a party for his best friend Casey. He needs to order enough chairs for all the party guests to sit in, one for each guest. First he orders 3 dozen chairs for 3 dozen guests he invites. Then he finds out that 1/3 of the guests want to bring a guest of their own, so Thomas needs to order more chairs. Eventually, Thomas finds out that 5 of the guests he originally invited can't make it. Thomas would also like to order 12 extra chairs just in case they need them. How many chairs is Thomas going to order for Casey's party?
[Answer]Thomas originally orders chairs for 3 dozen guests, 12 x 3 = 36 guests. Thomas finds out that 1 / 3 of the guests want to bring a guest of their own, 1 / 3 of 36 = 12. The 12 guests bring a guest of their own each, 36 guests + 12 guests = 48. Thomas finds out that 20 of the guests can't make it, 48 guests - 5 guests = 43. Thomas wants to order an extra 12 chairs, 43 + 12 = 55. Thomas will need 55 chairs for the party. The answer is 55.

Q: A married couple opened a savings account. The wife committed to saving $100 every week while the husband committed to saving $225 every month. After 4 months of savings, they decided to invest half of their money in buying stocks. Each share of stocks costs $50. How many shares of stocks can they buy?
A: The wife saves $100 / week x 4 weeks / month = $400 a month. Together, the wife and husband save $400 / month + $225 / month = $625 / month. In 4 months, their total savings is $625 / month x 4 months = $2500. They are going to invest $2500 / 2 = $1250. So, they can buy $1250 / $50 / share = 25 shares of stocks. The answer is 25.
