use the total revenue test to determine whether the demand for home heating oil is elastic or inelastic and why

Home heating oil is considered inelastic demand instead of elastic demand. Inelastic demand is when people will buy the same amount whether the price of the good drops or rises. People who buy home heating oil want their homes to be kept heated and warm, since they are buying it to serve a purpose like this, whether the price rises or drops they still will need it. Since they will need it regardless of price, they will continue to buy it and therefor it is inelastic.
