Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
The novelty shop on the Starship Conundrum sells magazines and chocolates.  The cost of four chocolate bars is equal to the cost of 8 magazines.  If one magazine costs $1, how much does a dozen chocolate bars cost, in dollars?

### Response:
If one magazine costs $1, then 8 magazines cost 8*$1=$<<8*1=8>>8.
Let's define "x" as the cost of one chocolate bar.
The cost of four chocolate bars is equal to the cost of 8 magazines and 4*x=$8.
Dividing each side of the equation by 4, we get the cost of one chocolate bar x=$2.
Therefore, a dozen chocolate bars would cost x*12=$24.
