 * Measure of Central Tendency**

the mean = 50 the median = 31 the mode = 31


 * Square Root**

A) 69 = 8 and 5/17 B) 31 = 5 and 6/11 C) 117 = 10 and 17/21


 * Percantage**
 * Is taking 15% off a given item and then an additional 10% off the reduced price the same as taking 25% off the orignal price? Why or why not.**

__-first part: 15% off then -10%__ -lets say something costs $100 -100/100x15=15 -100-15=85 -85/100=8.5 -85-8.5=**76.5**

__-second part: 25% off__ -100/100x25=25 -100-25=**75**

76.5>75

They are different because in part one, you don't find the same percent anymore, because you find the percent of another number, rather than just 100%. Taking 25% off will take off more.

x k y 45 x 1.89 = 85 27 x 1.89 = 51 answer is 51

Qustion 5) find what x = 20

7 x2 =14 10x2 =20
