Okay, here we have this:
Considering the provided information we obtain that:
$1140 is x%
$190,000 is 100%
So, here we have the following proportion:
[tex]\frac{190000}{1140}=\frac{100}{x}[/tex]Now, let's solve for x:
[tex]\begin{gathered} x=\frac{1140\cdot100}{190000} \\ x=\frac{114000}{190000} \\ x=\frac{3}{5} \\ x=0.6 \end{gathered}[/tex]Finally we obtain that the tax rate was 0.6%.
