Since there are 52 weeks in a year, we find her weekly paycheck amount by dividing her total salary, 32200, by 52: 32200/52 ≈ $619.23 (we round to the nearest cent) She takes 6% of her check and invests it in her 401(k). 6% = 6/100 = 0.06. We multiply her weekly check amount by 0.06 to find how much was invested each week: $619.23(0.06) ≈$37.15 (again round to the nearest cent).
