Question: Mike has earned a total of $160 in wages this week. He received the wages for his first job, then later received the wages from his second job where he works 12 hours a week. If his second job pays $9 per hour then how much money, in dollars, did Mike receive from his first job?
Answer with step-by-step thinking: From his second job, Mike receives $9 / hour * 12 hours = $108. He therefore earned $160 – $108 = $52 from his first job.
So the answer is 52.


Question: Bob ordered 80 packs of Greek yogurt from Costco to use for the month. However, when the delivery arrived, he realized 40% of the packs were expired. He decided to return those packs. If each pack was $12, how much was Bob refunded for the expired product?
Answer with step-by-step thinking: The number of Greek yogurt packs that had expired is 40 / 100 * 80 = 32. If each pack of Greek yogurt was sold at $12, for the 32 packs of greek yogurt that he returned, Bob was refunded $12 * 32 = $384.
So the answer is 384.


Question: Kaylin is five years younger than Sarah, who is twice as old as Eli, who is nine years older than Freyja. If Freyja is ten years old, how old is Kaylin?
Answer with step-by-step thinking:
Since Freyja is ten years old, Eli is 10 + 9 = 19 years old. Sarah's age is twice Eli's, then Sarah is 2 * 19 = 38 years old. Kaylin is five years younger than Sarah, then she is 38 - 5 = 33 years old.
So the answer is 33.
