Answer 1

Answer:

$\ 3000+\ 6000=\ 9000$

Step-by-step explanation:

He has a raise of $400 at the end of each year, the we have to find how much is the total amount raised during the 15 years, then:

$\ 400\times 15=\ 6000$

The during the 25 years he has a total raised of $6000 as the salary during the first years was $3000, the salary during the 15th year is:

$\ 3000+\ 6000=\ 9000$
