Question 1110515
A used car salesperson is paid a commission of $25 plus 40% of the selling price in excess of owners cost. The owner claims that used cars typically sell for at least owners cost plus $200 and at most owners cost plus $3000. For each sale made, over what range can the salesperson expect the commission to vary? 
-----
oc+200 <= selling price <= oc+3000
-----
25+1.4(200) <= commission <= 25+1.4(3000)
-----
25+280 <= commission <= 4225
=====
Ans: 305 <= commission <=4225
