A family went out to see a movie. The regular ticket costs $9 and the ticket for children is $2 less. They gave the cashier two $20 bills and they received a $1 change. How many children are there if there are 2 adults in the family? Give the rationale and then the answer.
Let's think step by step. They gave the cashier $20 x 2 = $40. Since a $1 change was returned, this means the tickets cost $40 - $1 = $39. Two adult tickets cost $9 x 2 = $18. So, $39 - $18 = $21 was spent for the children's tickets. Each child's ticket costs $9 - $2 = $7. Therefore, there are $21 / $7 = 3 children.. The answer is: 3.

Cersei bought 50 cotton candies. She gave her brother and sister 5 cotton candies each, then gave the remaining one-fourth of them to her cousin. If she ate 12 cotton candies, how many cotton candies are left? Give the rationale and then the answer.
Let's think step by step. Cersei gave a total of 5 x 2 = 10 cotton candies to her brother and sister. So, the total cotton candies left were 50 - 10 = 40. And she gave 1 / 4 x 40 = 10 cotton candies to her cousin. So, the total number of cotton candies left was 40 - 10 = 30. Therefore, the total number of cotton candies left after she ate 12 of them is 30 - 12 = 18.. The answer is: 18.

Dabbie bought 3 turkeys for thanksgiving, the first turkey is 6 kilograms, the second turkey is 9 kilograms, and the weight of the third turkey is twice the weight of the second turkey. If the cost of a kilogram of turkey is $2, how much does Dabbie spent on all the turkeys? Give the rationale and then the answer.
Let's think step by step. Dabbie paid 6 x $2 = $12 for the first turkey. He paid 9 x $ 2 = $18 for the second turkey. And the weight of the third turkey is 9 x 2 = 18 kilograms. So, the price of the third turkey is 18 x $2 = $36. Therefore, the total amount he paid for all the turkeys is $12 + $18 + $36 = $66.. The answer is: 66.
