Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Kwanza tafuta jumla ya miaka Wendy alitumia katika uhasibu: miaka 25 + miaka 15 = <<25+15=40>>40 miaka
Kisha gawanya idadi ya miaka aliyotumia katika uhasibu na idadi ya miaka aliyoishi na kuzidisha na 100% ili kupata asilimia ya maisha yake: 40 miaka / 80 miaka * 100% = 50%
