“Use a cell reference or a single formula where appropriate in order to receive full credit. Do not copy and paste values or type values, as you will not receive full credit for your answers.

Start Excel.”
In cell E10, by using relative and absolute cell references, calculate the point price elasticity of demand at the price in cell C10 and the quantity in cell D10. Copy the formula from cell E10 down the column to cell E28.
“In cells H31 and J31, by using cell references, enter the range of prices at which the demand curve is inelastic.
