Question 444968: Use an inequality to solve the problem. Be sure to show the inequality and all of your work.
A salesperson has two job offers. Company A offers a weekly salary of $90 plus commission of 6% of sales. Company B offers a weekly salary of $180 plus commission of 3% of sales. What is the amount of sales above which Company A’s offer is the better of the two?

You can put this solution on YOUR website!
Let s = amount of weekly sales
The inequality is
( company A's offer ) > (company B's offer )
given:
+90+%2B+.06s+%3E+180+%2B+.03s+
+.06s+-+.03s+%3E+180+-+90+
+.03s+%3E+90+
+s+%3E+3000+
If the amount of sales is greater than $3,000,
company A's offer is better
check answer:
Suppose amount of sales is $3,001
+90+%2B+.06s+%3E+180+%2B+.03s+
+90+%2B+.06%2A3001+%3E+180+%2B+.03%2A3001+
+90+%2B+180.06+%3E+180+%2B+90.03+
+270.06+%3E+270.03+
OK
