An integer, x = 160 is added a random number, n, ten times. Where n can be 1 - 10. The probability of n ≤ 5 is 50%, and it will increase by 5% for every subsequent increase of 5 to the integer.
The probability of n > 5 is 50%, and it will decrease by 5% for every subsequent increase of 5 to the integer.

Find the probability of the integer, x ≥ 200. ​​

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
