![x^{\frac{p}{r}}=\sqrt[r]{x^{p}}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7Bp%7D%7Br%7D%7D%3D%5Csqrt%5Br%5D%7Bx%5E%7Bp%7D%7D)
![3a^\frac{5}{3} =\sqrt[3]{3a^5}](https://tex.z-dn.net/?f=3a%5E%5Cfrac%7B5%7D%7B3%7D%20%3D%5Csqrt%5B3%5D%7B3a%5E5%7D)
Percent means per 100
think cent as in 100 pennies in a dollar
To convert from percent to decimal, we divide by 100 or move the decimal over 2 spots, so,
15% = 15/100 = 0.15
Now multiply 0.15 by 850 to find the discount saved
0.15*850 = 127.50
So you'll save $127.50
The final price is therefore: 850-127.50 = 722.50
A shortcut is to multiply 850 by 0.85
850*0.85 = 722.50
We get the same answer
The 0.85 comes from the fact that if you get 15% off, then you pay 85% of the original price
