Finance math question

Question

Roseanne works at a local shop for 30 hours per week. She makes $12 an hour, which is California's minimum wage as of 2019. Taxes (federal, state, and social security) deduct 28% of her gross pay. She then takes 10% of her take-home pay and puts it into a savings account. This leaves her with how much money to spend each week?

Write out your work, using both mathematical notation (30 * 12 = 360), as well as words (This means she makes a total of $360 per week). Write your final answer in a complete sentence.

Answer 1

Formula =(($12 * (1-.28)) * 30) * (1-.90)) = $233.28

Roseanne will take home 72% ( 100 - 28%) of the $12 per hour wage after considering taxes. If she works 30 hours per week, she will make $259.20 after tax. If she takes 10% and puts it in a savings account, that leaves her with 90% of her take home pay ($259.20) to spend, which is $233.28.
