Iused an rx savings card the prescription normally would be $11.00 with the free discount card i only paid $7.00. what was my percentage of savings using the free rx savings card?

  =36.36 percent

Step-by-step explanation:

First we need to determine what you saved

11-7 = 4

You saved 4 dollars

Percentage of savings = savings /original price * 100

                                      = 4/11 * 100

                                       =36.36 percent

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.
