Answer:
$87.5 more did Alex earn in one month than Ben
Explanation:

Last year Alex earned a monthly salary of $250,and Ben earned monthly salary of $180.
This year, each of them received a pay increase of 25% .
25% is written in the decimal form.

Increase in the Alex salary this year = 0.25 × Last year salary
= 0.25 × 250
= $62.5
Total amount of Alex salary this year for one month = Last year salary + Increase in the Alex salary this year
= 250 + 62.5
= $ 312.5
Thus the salary earn by the Alex this year for a month be $312.5.
Increase in the Ben salary this year = 0.25 × Last year salary
= 0.25 × 180
= $45
Total amount of Ben salary this year for one month = Last year salary + Increase in the Ben salary this year
= 180 + 45
= $ 225
Thus the salary earn by the Alex this year for a month be $ 225 .
Amount Alex earn in one month than Ben = Total amount of Alex salary this year for one month - Total amount of Ben salary this year for one month
Putting the values in the above
= $ 312.5 - $225
= $ 87.5
Therefore $87.5 more did Alex earn in one month than Ben .
