[Question]: My dog was born when I was 15 years old. Two years from now, my dog will turn 4 years old. How old am I now?
[Answer]: In 2 years, my dog will be 4 years old, so my dog is 4 - 2 = 2 years old now. So I am 15 + 2 = 17 years old now.

[Question]: Half of Taylor's house guests like weak coffee and the other half like strong coffee in the morning. Taylor uses 1 tablespoon of coffee per cup of water to make it weak and he doubles that amount to make it strong. If he makes 12 cups of both weak and strong coffee, how many tablespoons of coffee will he need?
[Answer]: He uses 1 tablespoon for weak coffee and doubles that for strong so the strong uses 1 * 2 = 2 tablespoons. For the weak coffee he uses 1 tablespoon per 1 cup of water and he needs to make 12 cups so he'll use 1 * 12 = 12 tablespoons. For the strong coffee he uses 2 tablespoons per 1 cup of water and he needs to make 12 cups so he'll use 2 * 12 = 24 tablespoons. All total he will use 12 tablespoons for the weak coffee and 24 tablespoons for the strong coffee for a total of 12 + 24 = 36 tablespoons.
So the answer is 36.

[Question]: Pat is buying supplies for S'mores. He and his friends will each eat 3 S'mores. There are 8 of them in total. It costs $3 in supplies to make 4 S'mores. How much will it cost to buy all the supplies?
[Answer]:
They are making 24 S'mores because 8 x 3 = 24. Each S'more costs $.75 to make because 3 / 4 = .75. It will cost $18 to make them all because 24 x .75 = 18.
So the answer is 18.
