Q: 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?
A: 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.
Question: Kelly puts string cheeses in her kids lunches 5 days per week. Her oldest wants 2 every day and her youngest will only eat 1. The packages come with 30 string cheeses per pack. How many packages of string cheese will Kelly need to fill her kids lunches for 4 weeks?
Answer: Her oldest wants 2 strings cheeses a day for 5 days so 2 * 5 = 10 string cheeses. Her youngest wants 1 string cheese a day for 5 days so 1 * 5 = 5 string cheeses. Together they want 10 + 5 = 15 string cheeses a week. Over 4 weeks, her kids will eat 15 string cheeses so 4 * 15 = 60 string cheeses. The bags have 30 per pack and she needs 60 so 60 / 30 = 2 packs of string cheese. The answer is 2.

For the fruits, the company needs to pay 3 * 2 = $6 per batch. 10 liters of milk is a cost of 10 * 1.5 = $15 for the company. So in total one batch is a cost of 15 + 6 = $21. So three batches of yogurt is a cost of 3 * 21 = $63. The answer is 63.
