1) calculate 12% of 3000 3000=100% x=12% 3000•12=100•x x=360 2) calculate 3% of 3000 3000=100% y=3% 3•3000=100y y=90 3) calculate 1% of 3000 3000=100% z=1% 3000•1=100z z=30 4) calculate 6% of 3000 3000=100% k=6% 3000•6=100k k=180 5) now we need to add all this numbers to each other to see total money he has to spend in taxes (but we will take 180 twice because there where two 6%_s) 360+90+30+180+180=840 6) to calculate his take-home pay, we need to subtract 3000 by tax pay that we just calculated 3000-840=2160
