Kedar earns a monthly salary if $2,200 plus a 3.75% commission on the amount of his sales at a men's clothing store. What would
ryzh [129]
Monthly salary of Kedar = $2000
Percentage commission on the amount of his sales = 3.75%
Amount of money for which clothing sold by Kedar = $4500
Amount of interest earned by Kedar this month = (3.75/100) * 4500
                                                                            = 3.75 * 45
                                                                            = 168.75 dollars
So
The total amount earned by Kedar this month = (2200 + 168.75) dollars
                                                                          = 2368.75 dollars
So Kedar earned a total amount of $2368.75 this month.I hope the procedure is absolutely clear to you.

Jordana wrote the equation for a linear relationship as y = -8x-4. For what value of x is y equal to -16
victus00 [196]
So our two equations are y=-8x-4 and y=-16, and since in both equations, something equals the same y, those two are the same. So we can combine the two into -16=-8x-4. In the question, they are asking to solve for x. So to do that, you need to isolate your variable. Now for solving algebraic equations, you use reverse PEMDAS (SADMEP), meaning you add 4 to both sides to clear the -4 one the rights side to get -12=-8x. Then you divide both sides by -8 to get 12/8, which simplifies to 3/2.
