Question 1083674
The increase is $49,000 - $35,000 = $14,000.
As a fraction of the original salary the increase is
{{{14000/35000=14/35=2/5=0.4=40/100}}} .
For every 100 the worker earned before,
there will be an increase of 40 on becoming a teacher.
That is 40% exactly.
To the nearest tenth of a percentage point, it is
{{{highlight("40.0%")}}} .
