Answer:
Tennessee
Step-by-step explanation:
First, let's find out how much tax he paid...
$695.49-$649.99=$45.50
We can use this to set up an equation...
x%(649.99)=45.50
We can convert x% to x/100 since any percentage is just that number over one hundred...

Multiply 100 to both sides

Divide both sides by 649.99

This is closest to 7 (our answers is not exact since you can only have two decimal places in money), therefore he lives in D. Tennessee
