Joe runs a successful hot dog stand. Joe has to order his hot dogs, buns, mustard, relish, and all other condiments in bulk, as well as pay taxes, licensing fees, and other small business expenses. Therefore, Joe has a relatively large "sunk" cost associated with his business - it averages out
to $950 per week just to keep the cart open. The cost of producing hot dogs is given by C(x)=950 + .45X
If he sold 100 hotdogs at $10.25 each, how much profit would he make for the week?
