Answer:
$250
Step-by-step explanation:
You can imagine the price of 212.5 to be 85% of the original price (100 - 15), so to do this, an easy way to find 100% is to simply divide the amount by the percentage:
Amount ÷ ![\frac{percentage}{100}](https://tex.z-dn.net/?f=%5Cfrac%7Bpercentage%7D%7B100%7D)
Simply plug the values in:
212.50 ÷ (![\frac{85}{100}](https://tex.z-dn.net/?f=%5Cfrac%7B85%7D%7B100%7D)
= 250
So the price of the tablet before markdown was $250!

Answer:
SOLUTION:-
- Let,last year population be x.
- We have last year population+Increased population=10,800
![x + 8\% \: of \: x = 10800](https://tex.z-dn.net/?f=x%20%2B%208%5C%25%20%5C%3A%20of%20%5C%3A%20x%20%3D%2010800)
![\displaystyle{x + \frac{8x}{100} = 10800 }](https://tex.z-dn.net/?f=%5Cdisplaystyle%7Bx%20%2B%20%20%5Cfrac%7B8x%7D%7B100%7D%20%3D%2010800%20%7D)
![\displaystyle{ \frac{100x + 8x}{100} = 10800}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20%5Cfrac%7B100x%20%2B%208x%7D%7B100%7D%20%20%3D%2010800%7D)
![\displaystyle{ \frac{108x}{100} = 10800}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20%5Cfrac%7B108x%7D%7B100%7D%20%20%3D%2010800%7D)
![108x = 10800 \times 100](https://tex.z-dn.net/?f=108x%20%3D%2010800%20%5Ctimes%20100)
![108x = 1080000](https://tex.z-dn.net/?f=108x%20%3D%201080000)
![x = \displaystyle{ \frac{1080000}{108} }](https://tex.z-dn.net/?f=x%20%3D%20%5Cdisplaystyle%7B%20%5Cfrac%7B1080000%7D%7B108%7D%20%7D)
![x = 10000](https://tex.z-dn.net/?f=x%20%3D%2010000)
Therefore,required last year population=10000
Step-by-step explanation:
Non examples are:
y= 1/2 x - 3
y = x - 2
x = 6y
Examples are:
5x - 3y = 9
2x + 3y = 0
x + y = 1
there are 5 significant figures
