 * __Question 1)__**
 * __4,4,6,7,8,9,9,21__**
 * __Mode__** : 4 and 9
 * __Median__** : 8 because it's the number in the middle.
 * __Mean :__** **4+4+6+7+8+9+9+21 = 68 > 68 / 8 = 8.5**
 * __Question 2)__**

No, because if the given price was $ 100 then 100 x 0.15 = $15 100 - 15 = $85 85 x 0.10 = 8.5 85 - 8.5 = $76.50 100 x 0.25 = $25 25 - 100 = %75 Because when you take away 25%, your taking it away from the whole 100. But when your breaking the 25% down, you are not taking away from the 100. 15% off 100 = 85, and your taking 10% from the 85, which is 8.5. And then 85 - 8.5 = $76.50. So the answer is $76.50.
