Answer:
[tex]Tennessee \ at \ 7\%[/tex]
Step-by-step explanation:
First we calculate the tax rate in each state:
Iowa Tax Rate
[tex]T_t=\frac{47.70-45}{45}\times100\%\\=6\%[/tex]
Tennessee Tax Rate,
[tex]T_t=\frac{37.45-35}{35}\times100\%\\=7\%[/tex]
From our calculations it's clear than Tennessee has the highest tax rate of the two at 7% to Iowa's 6%
Hence Tennessee has a greater sales tax percentage.
