Econ hw help!please?!?

Just do the graphs, trace the suply then the demand then move the supply $20 up on account of the tax the new intersection es the price paid by the buyers, draw a line straight down from the new intersection, the intersection of this line with the original supply is the price recived by the producer, the goverment tax revenue is 20*quantity of corn sold, the deadweight loss is the lil triangle in there. Use math to calculate its area
