Zainab earns $2 an hour passing out flyers at the town square. She passes out flyers on Monday, Wednesday, and Saturday each week, for 4 hours at a time. After passing out flyers for 4 weeks, how much money will Zainab earn? Give the rationale and then the answer.
Let's think step by step. Every day Zainab passes out flyers, she earns $2 x 4 = $8. If she hands out flyers for 3 days, she'll earn $8 / day * 3 days = $24. If she passes out flyers for 4 weeks, she will earn $24 * 4 = $96.. The answer is: 96.

Frank has three less than half the number of cookies as Mike. Mike has three times as many cookies as Millie. If Millie has 4 cookies, how many cookies does Frank have? Give the rationale and then the answer.
Let's think step by step. Mike has 4 * 3 = 12 cookies. Frank has 12 / 2 - 3 = 3 cookies.. The answer is: 3.

Lorie has 2 pieces of $100 bills. He requested to change one piece of the $100 bills into $50 bills. Half of the remaining $100 bill is changed to $10 bills while the rest is changed to $5 bills. How many pieces of bills will she have? Give the rationale and then the answer.
Let's think step by step. There will be $100 / $50 = 2 pieces of $50 when $100 is changed to $50 bills. Half of $100 is $100 / 2 = $50. So there will be $50 / $10 = 5 pieces of $10 when $50 is changed to $10 bills. The remaining $50 will be changed to $5 bills so there will be $50 / $5 = 10 pieces of $5 bills. So in total, Lorie will have 2 $50 bills + 5 $10 bills + 10 $5 bills = 17 pieces of bills.. The answer is: 17.
