5.If the cross-price elasticity of demand between two items is positive, the two items are substitutes.
6.If an item is extremely insignificant in your budget, your demand for the item is likely to be very inelastic.
7.If the quantity demanded is 6 units per week at a price of $3 per unit and 10 units per week at a price of $2 per unit, the demand between the two points on the demand curve is elastic.
