Mae’s Country Kitchen sells out of cinnamon rolls every morning before 8:30 a.m., and customers continue to ask for them. Mae decided to make an additional two dozen cinnamon rolls and raise the price of an individual cinnamon roll by 50¢. She sold all but one of them. Mae has found the ________ price for her cinnamon rolls, where supply equals demand.
