Find the sales tax and total cost of an espresso machine that costs $31.95 . The tax rate is 7%. Round your answer to the nearest cent.

Ok, so
We know that the tax rate is 7%, so, the sales tax will be:
($31.95 * 7) / 100
Which is equal to $2.24.
Now, the total cost will be the sum of the initial cost and the sales tax, which is:
($31.95 + $2.24), and this is $34.2
