we are given
Mr. Tomaszewski earned 2,000 zlotys
so, past salary =2000
he got a raise and currently earns 2,500 zlotys
so, present salary =2500
now, we have to find raised amount
we can use formula
raised amount = (present salary) - (past salary)
now, we can plug values
and we get
raised amount = 2500 - 2000
so, we get
raised amount = 500 zlotys........Answer
