<human>:  Wendy spent 25 years as an accountant and 15 years as an accounting manager. If Wendy lived to be 80 years old, what percentage of her life did she spend in an accounting-related job?
<bot>: How many years did Wendy spend in accounting? ** First find the total number of years Wendy spent in accounting: 25 years + 15 years = <<25+15=40>>40 years
How many years did Wendy spend in accounting? ** Then divide the number of years she spent in accounting by the number of years she lived and multiply by 100% to find the percentage of her life: 40 years / 80 years * 100% = 50%
