Total Revenue

When price increases, total revenue increases decreases remains unchanged( increases, decreases, remains unchanged ) for price inelastic goods and increases decreases remains unchanged( increases, decreases, remains unchanged ) for elastic goods.
When price decreases, total revenue increases decreases remains unchanged( increases, decreases, remains unchanged ) for price inelastic goods and increases decreases remains unchanged( increases, decreases, remains unchanged ) of elastic goods.
In both cases, total revenue remains unchanged increases decreases( remains unchanged, increases, decreases ) for unitary goods.
