Jill works as a waitress at the local diner where she earns an hourly wage of $6.00 per hour and a standard tip rate of 35% of the cost of the orders she serves. If she worked four 10-hour shifts this week and averaged $40 in orders per hour, how much did Jill earn this week?  Select:	A) 280	B) 300	C) 320	D) 350	E) 1120
Jill earns 6 dollars/hour and the hourly tip is (7/20)*40.   Jill thus earns 6*10+10*14 per day(or 6(10)+14(10)=20(14)=280).   Jill has worked for 4 days -&gt;280*4=1120.   This matches answer choice 1120.
