Hey there, I'm trying to learn about elasticity, but for some reason, how I need to use the formula just won't click. Can someone help me by working out this problem and explaining the process step-by-step so that I know how to effectively use the elasticity of demand equation in the future? Thanks!

Demand for Iced Coffee 5.0 4.5 4.0 3.5 3.0 Price (dollars) 2.5 2.0 1.5 1.0 0.5 0 50 100 150 200 250 300 350 400 450 500 b. Using the starting point method, what is the price elasticity of demand from a price of $2.50 to a price of $3.00 per iced coffee? , and demand is said to be price: (Click to select) v (Click to select) c. Using the starting point method, what is the elastic of demand from a price of $0.50 to a price of $1.00 per iced coffee? inelastic , and demand is said to be price unit-elastic
