###Human: 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?, ### Assistant: 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. 
 So the answer is :  66
