Human: A store offers sandwiches in 3 different package sizes: the first package with 2 sandwiches for $3, the second with 4 sandwiches for $6, and a third with 8 sandwiches, but the price is not indicated. Knowing that the prices are proportional, how much will the package with 8 sandwiches cost? Assistant: 
How much does one sandwich cost? ** So the price for 1 sandwich is $3 / 2 sandwiches = $<<3/2=1.5>>1.5/sandwich
How much would the package with 8 sandwiches cost? ** Now the price for the package with 8 sandwiches would be $1.5/sandwich * 8 sandwiches = $<<1.5*8=12>>12
