Answer:

Let

x= Mayor’s previous salary

y=his increased salary

5% increase means

(105/100)*x=y——-(1)

From the other reporter

The Mayor’s salary went up $2000

:. y-x=2000———-(2)

Put y= (105/100)*x into equation 2

105x/100 -x =2000

Multiply through by 100

105x-100x=200000

5x=200000

Divide both sides by 5

x=40000

Hence his previous salary was $40,000 and current one is

y=2000 +40000

y=$42000

Step-by-step explanation: from your question, you didn’t state whether it went up by 2000 or went to 2000. I chose went by 2000. If it were to be went to 2000 , the equation will be different. It would been 2000-x=y
