Answer:
b = 13
Step-by-step explanation:
5 + b = 18
-5. -5. -5 on both sides to get b by itself
I believe that this is the answer.
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.
