Okay, let’s tackle this. So Terria has 12 years of experience as an office administrator, which is a common role in architecture and engineering firms. According to national averages, office administrators with similar experience can earn around $40-$60 per hour. Considering the location is the United States, which has a relatively high cost of living, I'll estimate her hourly rate to be on the lower end of that range. Maybe around $45 per hour, given the lack of specific industry or location-based information.
