The price of tablet was $250 before mark down.
Step-by-step explanation:
Given,
Mark down = 15%
Price after mark down = $212.50
As price is marked down 15% from 100%, we can say that
(100-15)% = 85% is the price after markdown.
Let,
x be the original price.
Therefore,
85% of x = 212.50
![\frac{85}{100}x=212.50\\0.85x=212.50](https://tex.z-dn.net/?f=%5Cfrac%7B85%7D%7B100%7Dx%3D212.50%5C%5C0.85x%3D212.50)
Dividing both sides by 0.85
![\frac{0.85x}{0.85}=\frac{212.50}{0.85}\\x=250](https://tex.z-dn.net/?f=%5Cfrac%7B0.85x%7D%7B0.85%7D%3D%5Cfrac%7B212.50%7D%7B0.85%7D%5C%5Cx%3D250)

Answer:
15.92 rotations
Step-by-step explanation:
We need to find the circumference, then divide the distance of the driveway by the circumference.
C = (pi)(d)
C = (3.14)(16)
C = 50.24
400/50.24 = 7.971783 one way to the mailbox. Since it asks for the "journey to the mailbox", let's double it, giving us 15.9235669
First, find a common denominator. Since both 6, 3, and 4 can be multiplied into 12, that will be or denominator.
1/6 becomes 2/12
2/3 becomes 8/12
and 1/4 becomes 3/12
2/12 + 8/12 = 10/12
The answer is 1 1/12
