two questions-

1. if sam decidedd to buy more vegtables does this imply that there has been an increase in quantity demanded . please graph as well
2. a dealer has recently started using a foreign supplier of goods rather than a local one . this caused his cost to decrease and him to reduce prices . Is this an example of change in quantity supplied or just a change in supply? please graph

1.increase in quantity demanded

2.just a change in supply

how do you propose how to graph it on here. this is a text only forum?
