G A car rental agency rents 180 cars per day at a rate of 30 dollars per day. For each 1 dollar increase in the daily rate, 5 fewer cars are rented. At what rate should the cars be rented to produce the maximum income, and what is the maximum income

$33 per day

$5,445

Step-by-step explanation:

(30+x)(180-5x) = Income

Income = -5x² + 180x - 150x + 5400

I = -5x² + 30x + 5400

dI/dx = -10x + 30 = 0

x = 3

Rate: 30+3 = 33

Income = 33(180 - (5×3)) = 5445

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.
