02 A company sells widgets. The amount of profit, y, made by the company, is
related to the selling price of each widget, x, by the given equation. Using this
equation, find out what price the widgets should be sold for, to the nearest
cent, for the company to make the maximum profit.
y = -x2
= -X- + 1012 – 900

step-by-step explanation:

32.50-7.50=25

225/25=11

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.

it would take 7/10 of an hour too fill the pool.
