9. you are the sales manager for solar panel company. you receive a commission

based on the total sales of all the salespeople you manage. your commission is

2 percent of the first $80,000 of sales, 4 percent of the next $80,000, and 5 percent

of all sales over $160,000. what is your commission for a month in which your

salespeople sold $242,100 in solar panels?

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.

thus, the first answer choice, y = sec x, is the correct one
