Answer:
The answer is 5.7%
Explanation:
So Peter bought the makeup set that was $30.
and had to pay $1.71.
1.71 of 30.
So you would divide 1.71 with 30.
(1.71/30)
equaling .057
Then you would multiply by 100 because there is 100% total, and so multiplying that you would move the decimal two times to the right, getting 5.7
