Answer the following question.
The total age of the people in Kaydence's family is 200. If Kaydence's father is 60 years old, Kaydence's mother 2 years younger than Kaydence's father, Kaydence's brother 1/2 the age of Kaydence's father, and Kaydence's sister 40 years old, how old is Kaydence?
Step-by-step reasoning process: If Kaydence's father is 60 years old, her mother is 60 - 2 = 58 years old. The total age of the mother and father is 60 + 58 = 118 years. Kaydence's brother is half the father's age, which is 1 / 2 * 60 = 30 years. The total age of Kaydence's father, mother, and brother is 30 + 118 = 148 years. If you add Kaydence's sister's age to the total age of the father, mother, and brother, you get 148 + 40 = 188 years. If everyone's age in the family is 200, then Kaydence's age is 200 - 188 = 12 years old.
The answer is 12.

Answer the following question.
The price of a book was $400. If the book's price is decreased by 15% and then increased by 40%, what is the final price of the book?
Step-by-step reasoning process: When the price of the book is decreased by 15%, the total price decrease is 15 / 100 * $400 = $60. The new price of the book becomes $400 - $60 = $340. The price of the book is then increased by 40 / 100 * 340 = $136. The final price of the book is $340 + $136 = $476.
The answer is 476.

Answer the following question.
A supplier is packing cartons of canned juice. Each carton has 20 cans of juice. Out of the 50 cartons that have been packed, only 40 cartons have been loaded on a truck. How many cans of juice are left to be loaded on the truck?
Step-by-step reasoning process: There are 50 - 40 = 10 cartons of canned juice that are left to be loaded on the truck. This is equal to 10 x 20 = 200 cans of juice.

Answer the following question.
Maddie wants to see how much her mom spends on coffee each week. She makes herself 2 cups of coffee per day. Each cup has 1.5 ounces of coffee beans. A bag of coffee costs $8 and contains 10.5 ounces of beans. She uses 1/2 a gallon of milk per week. A gallon of milk costs $4. She doesn't add any sugar to the coffee. How much does she spend on her coffee per week?
Step-by-step reasoning process: She uses 3 ounces of beans per day because 2 x 1.5 = 3. She uses 21 ounces of beans per week because 7 x 3 = 21. She buys 2 bags of beans per week because 21 / 10.5 = 2. She spends $16 on the beans per week because 2 x 8 = 16. She spends $2 on the milk per week because 4 x (1 / 2) = 2. She spends $18 per week on her coffee because 16 + 2 = 18.
The answer is 18.
