Sally Sells Sea Shells by the Sea Shore and collects all sales data. Now she is curious to find out what the elasticity of demand is for her shells. Assume they are all the same type and quantity. She scatter plots the data and finds there is a linear relationship that looks ripe for a regression estimation of the price response function for her shells. The slope of her regression line is 74. Currently, her average daily price is 14.69 and she sells 79 quantity at that price. Calculate the point elasticity of demand for her sea shells
