 * What is the Square Root of 45?**

=Percent= Is taking 15% off a given item and then an additional 10% off the reduced price the same as taking 25% off the original price? why or why not?
 * **No it is not the same because ...**

taking 15% off an item
example: 15% of $30 = $25.50 30 / 100 =0.3 x 15= $4.50 $30 - $4.50 = $25.50

AND AN ADDITIONAL 10% OFF THE REDUCED PRICE ($25.50 in this case)
example: 10% of $25.50 = $22.85 25.5 / 100 =0.255 x 10= $2.55 $25.50 - $2.55 = $22.95

Taking off 15% and then another 10% off the reduced price is not the same as taking off 25% alone. So I'd say that 25% off is a better deal than 15% then another reduced 10%.
