Respuesta :

Answer:

$87.5  more did Alex earn in one month than Ben

Step-by-step explanation:

As given

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.

[tex]= \frac{25}{100}[/tex]

= 0.25

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 .
