can you help me these two problems. I submitted two because they two of the same questions.

Question 19. A,B,C

Let one week's supply and demand functions for gasoline be given by p = D(q) = 297 - 5 and p = S(q) = 7q, where p is the price in dollars and q is the number of 42-gallon barre (a) Graph these equations on the same axes. (b) Find the equilibrium quantity. (c) Find equilibrium price. (a) Choose the graph of D(q) and S(q). OA. O B. O C. O D.
