Okay, let’s calculate this. Maggie has 9+ years of experience in Accounts Receivable management, which is a specialized skill. In the US, according to various sources, including Glassdoor and Indeed, the average salary for an Accounts Receivable Manager with similar experience is around $60,000-$80,000 per year. However, considering her current role as a manager, I'll estimate her hourly rate to be slightly higher. Let’s assume a 40-hour workweek and 52 weeks per year, which is a standard full-time schedule. This translates to 2,080 hours per year. Using the average salary range, we can estimate her annual salary to be around $75,000. Now, let’s calculate her hourly rate: $75,000 / 2,080 hours ≈ $36 per hour. However, since she has 9+ years of experience, I'll add a 10%-20% premium to account for her expertise. This brings her hourly rate to around $40-$45 per hour. Considering the location is San Diego County, California, which has a relatively high cost of living, I'll round down to $65 per hour, assuming she's not in a highly competitive market.
