he city of Springfield has decided to reduce spending on road maintenance for next year. The decision saves the city $350,000. However, transportation experts tell the city that damaged roads could cost drivers up to $50,000 in extra vehicle repairs. The decision would also increase the average time spent commuting to work by 8 minutes per day. The additional time needed to travel over the poorly maintained roads is an example of an explicit cost. an implicit cost. an opportunity cost. a scarce resource.
