Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each sale
sman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900. On any given week, if Salesman B earns $1,020, how many sales did he have for the week?
