At a price of 2.24 per bushel, the supply of a certain grain is 7100 million bushels and the demand is 7800 million bushels. At a price of 2.35 per bushel, the supply is 7500 million bushels and the demand is 7700 million bushels. (A) Find a price-supply equation of the form p=mx+b where p is the price in dollars and x is the supply in millions of bushels. (B) Find a price -demand equation of the form p=mx+b where p is the price in dollars and x is the demand in millions of bushels. (C) Find the equilibrium point. (D) Graph the price -supply equation, price-demand equation, and equilibrium point in the same coordinate system. (A) The price-supply equation is p=square . (Type an exact answer.)

To find the price-supply equation of the form , we need to determine the slope (m) and the y-intercept (b).Given:At a price of 2.24 \ per bushel, the supply is 7500 million bushels.Step 1: Calculate the slope (m) using the given points (7100, 2.24) and (7500, 2.35).m = (2.35 - 2.24) / (7500 - 7100)m = 0.11 / 400m = 0.000275Step 2: Use one of the given points to solve for the y-intercept (b).Using the point (7100, 2.24):2.24 = 0.000275 * 7100 + bb = 2.24 - 1.95025b = 0.28975Therefore, the price-supply equation is:p = 0.000275x + 0.28975So, the answer for part (A) is:(A) The price-supply equation is .
