Question #52981

I am having problems plotting a supply and demand graph on excel just using an equation and also just creating graphs to show a shift in the demand or supply curve without any numbers. Also how to calculate relative price concerning two commodities.

Expert's answer

To plot a supply and demand graph on excel just using an equation you need to create a table with column "Q" and column "P" (in which you use equation provided to calculate P using Q). And then you should create a graph using points XY. If you need just creating graphs to show a shift in the demand or supply curve without any numbers, you need also to create a table, but with additional column for P1 (for the curve after the shift).

To calculate relative price concerning two commodities you just need to express one commodity using the other.
