Final answer:
Helen's salary increased more in absolute terms. Clint and Helen had the same percentage increase in their salaries.
Step-by-step explanation:
To determine whose salary increased more in absolute terms, we need to find the difference between the initial and final salaries for both Clint and Helen. Clint's salary increased from $20,000 to $28,000, so the absolute change is $28,000 - $20,000 = $8,000. Helen's salary increased from $27,000 to $37,800, so the absolute change is $37,800 - $27,000 = $10,800. Therefore, Helen's salary increased more in absolute terms.
To determine whose salary increased more in relative terms, we need to calculate the percentage increase. The formula for percentage increase is ((new value - old value) / old value) * 100. For Clint, the percentage increase is (($28,000 - $20,000) / $20,000) * 100 = 40%. For Helen, the percentage increase is (($37,800 - $27,000) / $27,000) * 100 = 40% as well. Therefore, both Clint and Helen had the same percentage increase in their salaries.
