Less than 1, and price and total revenue will move in the same direction

When the price of a good is $5, the quantity demanded is 100 units per month, when P is $7, Qd is 80 per month. Price elasticity of demand is:

.67

If sellers don't adjust their quantities supplied at all in response to a change in price,

Supply is perfectly inelastic

If the price elasticity of demand for a good is 4.0, then a 10% increase in price results in a:

40% decrease in quantity demanded

If the quantity supplied responds only slightly to changes in price, then

Supply is said to be inelastic

University is thinking about increasing tuition to enhance revenue. if they feel that will increase revenue they are:

Assuming that the demand for university education is inelastic

Buyers respond substantially to changes in the price of the good

Greater than 1
