Answer:
8/21
Step-by-step explanation:
Add up the fraction that is not shaded
2/7 + 1/3
Get a common denominator of 21
2/7 *3/3 + 1/3 *7/7
6/21 + 7/21
13/21
The entire circle is 21/21
Subtract the unshaded from the entire circle to get the shaded
21/21 -13/21
8/21
It would be $20.40 because 20% off of $28.00 is $22.4 - $2.00= $20.40
I think the answer is 38,068692.544
