Problema Solution

Sam earns $420 a week. She has 1/5 of her income withheld for federal taxes, and 1/20 of her income withheld for medical coverage. How much per week is left for Sam after those three deductions?

Answer provided by our tutors

420 - ((1/5)*420 + (1/20)*420) =


= 420 - 420(1/5 + 1/20) =


= 420(1 - 1/5 - 1/20) =


= 420((20 - 4 - 1)/20) =


= 420*(15/20) =


= $315


Sem has $315 per week left after the deductions.
