Sheila is hosting a large diplomatic event and needs to increase her inventory of dinnerware sets. She has set a $1925 budget and will choose dinnerware that will give her as much utility as possible. She shops online at Dinnerware Outlet and finds a deal for 30 sets of dinnerware on sale for $35 and she purchases them. A few days later, an email notifies her that another website called DinnerTime offers a deal for 35 sets of dinnerware for $25, while all other prices remain the same, and she snags them too. Given this information, plot Sheila's demand curve for plates and cups.
