Create a price vector along with supply and demand: Label cell D2 "price": In cells D3 to D23, enter values of prices ranging from 0 to 20 Label cell E2 "demand": In cells E3 to E23, use formulas and the "$" fixed reference notation to fix references to cells B3 and B4 as well as column D to calculate implied demand for each of the prices in column D. Label cell F2 "supply". In cells F3 to F23, use formulas and the "$" fixed reference notation to fix references to cells B5 and B6 as well as column D to calculate implied supply for each of the prices in column D
