Percentage denoted by the sign '%' means into hundred. So a percentage

is any number as multiplied by hundred. Hence 0.1 would be 1% as:

0.1*100=1

OR

1/100=0.1

In our case 7% can also be written as:

7/100

Which when simplified gives us:

0.07

In the question we are asked to find 7% of $676.6

For that we would multiply 676.6 with 0.07

So:

676.6*0.07

it can also be written as:

676.6*7/100

Which is:

473.62

So the state tax would be:

676.6-473.62

Which equals:

202.98

Hence the total amount of sales tax is 202.98
