<u>Answer:</u>
Helen's salary increased more.
<u>Step-by-step explanation:</u>
We know that Clint's salary increased from $24000 to $36000 over a three-year period.
So the increase in Clint's salary will be = 36000 - 24000 = $12000
While Helen's salary increased from $29000 to $43, 500 over the same period of 3 years.
So the increase in Helen's salary will be = 43500 - 29000 = $14500
Therefore, in absolute terms, Helen's salary has increased more.
