Bernie loves eating chocolate. He buys two chocolates every week at the local store. One chocolate costs him $3. In a different store, there is a long-term promotion, during which each chocolate costs only $2. How much would Bernie save in three weeks, if he would buy his chocolates in this store instead of his local one?

How many chocolates does Bernie buy in three weeks? ** During three weeks, Bernie buys 3 * 2 = <<3*2=6>>6 chocolates.
How much does Bernie pay in the local store? ** In the local store, he pays for them 6 * 3 = $<<6*3=18>>18.
How much would Bernie pay in the different store? ** If Bernie would buy the same chocolates in the different store, he would pay 6 * 2 = $<<6*2=12>>12.
How much would Bernie save in three weeks, if he would buy his chocolates in this store instead of his local one? ** So Bernie would be able to save 18 - 12 = $<<18-12=6>>6.
