$84.48 is incorrect

Nitai, who is single and has no dependents, was planning on spending the weekend repairing his car. On Friday, Nitais
				employer called and offered him $600 in overtime pay if he would agree to work over the weekend. Nitai could get his car
				repaired over the weekend at Autofix for $504. If Nitai works over the weekend, he will have to pay the $504 to have his
				car repaired but he will earn $600. Assume Nitai pays tax at a flat 12 percent rate.
				(Do not round intermediate calculations. Round your answers to 2 decimal places.)
				a-1. Strictly considering tax factors, should Nitai work or repair his car if the $504 he must pay to have his car fixed is not deductible?
	Work	600 x 12% = $60 , (600-72 = $528)
	Repair	$528 - 504) = $24
				a-2. Given the answer in a-1 above, by how much is Nitai better or worse off?
			$600 - 504 = $96
	Better-off	84.48	$96 x 12% = $11.52
