Trevor's weekly allowance is calculated using a point system. For each chore he does, Trevor gets a point. For each chore he misses, he loses a point. Each point is worth $2, and negative
points mean that Trevor owes money to his parents. If Trevor has a total of 8 assigned chores
each week, how much can he expect to earn or owe using this point system?
