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