Okay, let’s calculate Ann’s rate. Given her 45 years of experience, mostly in education, I would expect her rate to be lower than that of a typical writer or editor. Considering her extensive experience in teaching and proofreading, I would estimate her hourly rate to be around $75, which is a reasonable rate for a part-time or freelance writer or editor with similar experience and qualifications. This rate is also in line with the UK’s National Minimum Wage for older workers, which is around £7.50 per hour. However, as Ann has been working for 22 years, I would expect her rate to be slightly higher than the minimum wage, but not excessively so. $75 seems a fair estimate, taking into account her experience, qualifications, and location in the Greater Derby Area.
