Give the step-by-step reasoning process and then the final answer. Vikki worked 42 hours in one week. Her hourly pay rate is $10. From her weekly earnings, 20% is deducted as tax, 5% is deducted as insurance cover, and $5 is deducted for union dues. How much money, in dollars, does Vikki take home after deductions?
Vikki earnt 10 × $42 = $420 in one week. She then gets taxed $420 × 0.2 = $84. She also loses $420 × 0.05 = $21 due to insurance. Vikki also pays $5 in union dues. In total Vikki loses $84 + $21 + $5 = $110 because of deductions. Her final total pay after deductions is $420 - $110 = $310.
The final answer: 310.
