Question: Your video streaming subscription costs $14 a month. If you're evenly splitting the cost with your friend, how much do you pay in total after the first year for this service?
Answer: An even split is 50%. If the monthly subscription is $14, but I pay only 50% that means I pay every month $14 * 50% = $7. We know that in 1 year there are 12 months. Therefore if each month I pay $7, in 12 months I'd pay $7 * 12 = $84. The answer is 84.

[Question]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?
[Answer]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.
