How much money do Peter and Linda get from their parents every week?

Every week Peter and Linda receive five dollars from their parents. It is not a gift. Peter and Linda must work for the family to earn the money. Peter takes out the garbage and cleans the yard around the house. He should do it every day. But sometimes he forgets. Linda helps her mother with the cooking. She also washes the dishes after dinner. Peter and Linda don’t have to use their money for food. They use it for their entertainment. Sometimes they go to the movies; sometimes they buy records. Each week they save some of their money to buy something more expensive.
