complete devalue()'s recursive case: if value ≤ 60000.0, call devalue() to compute the next year's value as the current year's value multiplied by 0.9. otherwise, call devalue() to compute the next year's value as the current year's value multiplied by 0.8. ex: if the input is 50000.0, then the output is: year: 1, value: 50000.0 year: 2, value: 45000.0 year: 3, value: 40500.0 year: 4, value: 36450.0 year: 5, value: 32805.0 end of study
