Q: Louise is baking cakes for a gathering. She needs 60 cakes in total, and has already produced half this many. Today, she calculates how many cakes she has left to make and bakes half this amount. The next day, she again calculates how many cakes she has left to make and bakes a third of this amount. How many more cakes does Louise need to bake?
A: Louise has already produced 60 cakes / 2 = 30 cakes. After calculating how many cakes are left, she bakes another 30 cakes / 2 = 15 cakes. The next day, she calculates again then bakes another 15 cakes / 3 = 5 cakes. She therefore still needs to bake 60 30 15 5 = 10 cakes. The answer is 10.
Question: Jasper will serve charcuterie at his dinner party. He buys 2 pounds of cheddar cheese for $10, a pound of cream cheese that cost half the price of the cheddar cheese, and a pack of cold cuts that cost twice the price of the cheddar cheese. How much does he spend on the ingredients?
Answer: A pound of cream cheese cost $10 / 2 = $5. A pack of cold cuts cost $10 x 2 = $20. Jasper spent $10 + $5 + $20 = $35 on the ingredients. The answer is 35.

Q: Grandpa Lou enjoys watching movies on the Hallmark channel, where every movie lasts 90 minutes. If, on Tuesday, he watched several full-length movies on the Hallmark channel for a total of 4 hours and 30 minutes, and then on Wednesday he watched on the same channel twice as many movies as he did on Tuesday. What is the maximum number of full-length movies Grandpa could have watched during these two days?
A: 4 hours and 30 minutes is the same as 4 * 60 + 30 = 270 minutes. At 90 minutes per movie, Grandpa could watch a total of 270 / 90 = 3 entire movies in 4 hours and 30 minutes. On Wednesday, he watched 2 * 3 = 6 movies. Thus, during these two days, he could have watched as many as 3 + 6 = 9 movies. The answer is 9.
Question: Kristy, a sales representative earns a basic salary of $7.50 per hour plus a 16% commission on everything she sells. This month, she worked for 160 hours and sold $25000 worth of items. Her monthly budget for food, clothing, rent, transportation, bills and savings is 95% of her total monthly earnings and the rest will be put towards insurance. How much did she allocate to insurance?
Answer: Kristy earns a basic salary of $7.50 x 160 = $1200. Her total commission is $25000 x 16 / 100 = $4000. Thus, her total earning is $1200 + $4000 = $5200. Her monthly budget aside from the insurance is $5200 x 95 / 100 = $4940. Therefore, she allocated $5200 - $4940 = $260 on insurance. The answer is 260.
Q: Heather helps her neighbour pick weeds out of her garden. She gets paid 5 cents for every weed she picks. On average, how many seconds can she take to pick a weed if she wants to earn $10 an hour?
A:
In an hour, she needs to earn $10 * 100 cents / $1 = 1000 cents. In an hour, she must pick 1000 cents / 5 cents = 200 weeds. There are 1hr * (60 minutes / 1 hr) = 60 minutes in an hour. There are 60 minutes * (60 seconds / 1 minute) = 3600 seconds in an hour. She has 3600 seconds / 200 = 18 seconds to pick each weed. The answer is 18.
