Her store caters primarily to tourists passing through town on their way to Yellowstone National Park. Maria is unsure of how she should price her ice cream cones and has experimented with two prices in successive weeks during the busy August season. The number of people who entered the store was roughly the same in the two weeks. During the first week, she priced the cones at R1.89 and 1,500 cones were sold. During the second week, she priced the cones at R1,49 and 2,340 cones were sold. The variable cost of a cone is R0.43 and consists solely of the costs of the ice cream and of the cone itself. The fixed expenses of the ice cream stand are R675 per week. Estimate the price elasticity of demand for the ice cream cones. (Do not round intermediate calculations.
