Answer:
mode: number that appears most
mode=4 and 7
mean: =3+4+5+6+7+8+9+10+11÷9=7
so mean is 7
Z= (10/100) * 20
z=2 therefore 10% is $2
you do 20+2 because it was 10% off so you add the 10% to get the original price.
original price= $22
turn 8.5 into decimal
0.85 * 22 = 18.70 therefore there is a $18.70 tax.
You add 22+18.70 to find price after tax
after tax= $40.70
before tax= $22
(i really don't know if this is correct but there is a 95% chance this is right and a 5% chance it is wrong and if it is please forgive me)

Hello! Sauce B and C do not have he highest numbers and they were not any of the highest rated sauces. Therefore, A and B are eliminated.
