We have that the Medicare tax is 1.45% of gross pay, and the state tax is 1.5%. Then, if Hong Tang's gross weekly salary is $615, then::
[tex]\begin{gathered} (615)(0.0145)=8.92 \\ (615)(0.015)=9.22 \\ \Rightarrow8.92+9.22=18.14 \end{gathered}[/tex]therefore, from state tax and Medicare tax combined, Hong Tang gets deducted $18.14
