John made $40 commissions for $500 sales or 40/500. He wants $320 for an unknown amount of sales or 320/x.
40/500=320/x Cross multiply.
40x=160,000
Divide both sides by 40.
X=4,000
He needs his sales to be $4,000 to get $320 in commission.
Answer:
52.2%
Step-by-step explanation:
The total workforce is 11 + 12 = 23
Fraction of men = 
= 
To change the fraction to a percentage multiply the fraction by 100%
percent of men = × 100% = 52.2% ( to 1 dec. place )
I think you would do that
The equation is y = mx + b
(18, -19)
substitute these numbers in the equation
-19 = 0(18) + b
-19 is y because it is the y slot in the cordinate and I put 0 for m because m is the slope and x is 18
-19 = 0 + b
b= -19
the equation is
y = 0(x) - 19
y = -19
