Charlie's total earnings from his job are $45,000. He also earned $2,000 in profit from selling quilts. He pays $18 tax for every $100 in gross income. What is Charlie's net income?
Well he earned $47,000 which is 470*$100
He pays $18 tax for each $100 that is 18/100 = 18%
Tax = 18% of 47000
=18/100*47000
=$8460
net pay= 47000-8460=$38540
--------------------------
this is the same as (100-18)% of 47000 = 0.82*47000=$38540
