LOL, idk if this is right, but it is how i think it should be solved
<span>Rewrite the subtraction as addition 3- (-10)
= 3 + 10</span>
1st one: linear
2nd one: linear
3rd one: nonlinear
So bassically
his commision rate is
x% times 190000=comission
so x% times 190000=11400
divide both sdies by 190000
x%=11400/190000
solve for x percent
11400/190000=114/1900=3/50
x%=3/50
percent means parts out of 100 so x%=x/100
x/100=3/50
3/50=6/100
x/100=6/100
multiply both sdies by 100
x=6
the commision rate is 6%
