There is a group of 18 people who are ordering pizza. If each person gets 3 slices and each pizza has 9 slices, how many pizzas should they order?
Let's think: Each person eats 3 slices of pizza, the group in total eats 18 x 3 = 54 slices. There are 54 slices in 54 / 9 = 6 pizzas.. The answer is: 6.

Gwen received a $900 bonus at work and decided to invest this money in the stock market. She spent one-third of her bonus on stock A, one-third on stock B, and the remaining one-third on stock C.  After one year, stock A and stock B had doubled in value, while stock C had lost half of its value. At the end of the year, how much were Gwen's stocks worth, in dollars?
Let's think: One - third of her bonus was $900 / 3 = $300. After one year, stock A doubled in value and was worth $300 * 2 = $600. After one year, stock B doubled in value and was worth $300 * 2 = $600. After one year, stock C had lost half its value and was worth $300 / 2 = $150. Altogether, at the end of the year, Gwen's stocks were worth $600 + $600 + $150 = $1350.. The answer is: 1350.

Danny made chocolate cookies for his class and made sure each cookie had exactly 7 chips. He made 4 dozen in total. If the class eats half the cookies, how many chips are left uneaten?
Let's think: There are 48 cookies because 12 x 4 = 48. There are 24 cookies left because 48 / 2 = 24. There are 168 chips left because 24 x 7 = 168.. The answer is: 168.

A bag of dozen apples costs $14 and Brian has already spent $10 on kiwis and half that much on bananas. What's the maximum number of apples Brian can buy if he left his house with only $50 and needs to pay the $3.50 subway fare each way?
Let's think:
Brian requires a total of $3.50 + $3.50 = $7 to pay for the round trip subway fare. We also know he has spent half (1 / 2) the amount he spent on kiwis on bananas, so he'll spend (1 / 2) * $10 = $5 on bananas. So far in total he has spent $7 for his subway fare + $5 on bananas + $10 on kiwis = $7 + $5 + $10 = $22. If he left his house with only $50, then all he will have left for apples would be $50 - $22 = $28. If a bag of apples costs $14, then Brian would only be able to buy a maximum of $28 / $14 = 2 bags of apples. If each bag of apples has a dozen (12) apples, then (2) two bags will have 12 * 2 = 24 apples.. The answer is: 24.
