Phillipe works for a computer store that pays a 12% commission and no salary. what will phillipe's weekly sales have to be to earn $360

Well, we know what he earns is 12% of what he sells. If $360 is 12% we know that the value of what he sold multiplied by 0.12 is 360. Now we can write this out as an equation. i'm going to use X to represent the value of what he sold

X*0.12=360

now, we can solve for X by dividing by 0.12 on both sides

X=3000

(6,0) i hope it makes enough sense
