Rimadyl should not be combined with the use of any other NSAID, such as aspirin. In fact, the University of California-Davis veterinary program recommends a cooling off period of two weeks when switching from NSAIDs if Rimadyl or carprofen are involved.
Definition. An aggregate supply curve shows the quantity of all the goods and services that businesses in an economy will sell at a particular price level. In the long run, the aggregate supply curve is vertical, but the aggregate supply curve will be upward sloping in the short run.
Aggregate demand is the demand for domestic production--goods and services produced by the domestic economy. A change in the price level is a change in the price of this domestic production. Other countries in the foreign sector produce goods and services, too.
