(1)Missouri was International Shoe Corporation's principal place of business, but the company employed between 11 and 13 salespersons in the state of Washington.The state of Washington assessed the company for contributions to a state unemployment fund.The state served the assessment on one of International Shoe Corporation's sales representatives in Washington and sent a copy by registered mail to the company's Missouri headquarters.International Shoe's representative challenged the assessment on numerous grounds, arguing that the state had not properly served the corporation.Is the corporation's defense valid?Why or why not?

(2)A Louisiana resident Daniel Crummey, purchased a used recreational vehicle (RV) from sellers in Texas after viewing photos of it on eBay.The sellers regularly used eBay to market and sell vehicles to parties all over the country.The sellers' statements on eBayclaimed that "everything works great on this RV and will provide comfort and dependability for years to come.This RV will go to Alaska and back without any problems!"Crummeypicked up the RV in Texas, but on the drive home the RV quit working.He filed a suit in Louisiana against the sellers alleging that the vehicle was defective, but the sellers claimed that the Louisianacourt lacked jurisdiction.Are the sellers correct?Why or why not?
