Answer:

Step-by-step explanation:

Let x be last year's salary.

100%x + 8/100 x = 40120

100x/(100) + 8/100x  = 40120

108x/100 = 40120

1.08x = 40120

x = 40120/1.08

x = 37148.14

Now if you take 8% of  37148.14        =    2971.85

And add it to                                            37148.14

You should get the current earning      40119.99  

You are within a penny of the same answer. This question will not work out evenly because 1.08 does not divide evenly into 40120.
