A plumbing supplies manager realises he has a profit margin of 15%. His total sales for a month came $23,000. How much of this i
mart [117]
The percentage of profit margin that
the plumbing supplies manager realizes that he has = 15%
Total sales for the month made by the plumbing supplies manager = $23000
Then
Amount of profit that has been made
by the plumbing sales manager = 15% * 23000 dollars
                                                    = (15/100) * 23000 dollars
                                                     = 15 * 230 dollars
                                                     = 3450 dollars
So the plumbing manager makes a profit of $3450 in the month as can be seen from the above deduction.

A product means multiplication, so...

(x * -2) +8 = -4
-2x + 8 = -4

To isolate the x, we have a couple of different ways, but the easier for now would be to start off by moving the 8 to the other side via subtracting both sides by 8:
-2x + 8 - 8 = -4 - 8
-2x = -12

Next, we divide both sides by -2
-2x / -2 = -12 / -2
x = 6
