Answer:
tax rate = 43.76%
Step-by-step explanation:
Mariota's net income before taxes = $380,080 - $178,290 - $19,820 - $32,390 = $149,580
Mariota's net income after taxes = $69,626 + $14,500 = $84,126
$149,580 x (1 - tax rate) = $84,126
1 - tax rate = $84,126 / 149,580 = 0.5624
1 - tax rate = 0.5624
1 - 0.5624 = tax rate
tax rate = 0.4376 = 43.76%
