Suppose that the supply and demand equations for printed T-shirts for a particular week are given as follows, where p is the price in dollars and q is the quantity in hundreds. p = 0.9q + 1 Price-supply equation p -1.9q+18 Price-demand equation. Answer parts (A) through (D) below. (A) Find the supply and demand (to the nearest unit) if T-shirts are $5 each. To use the price-supply and price-demand equations to find the requested quantities, substitute $5 for p. The number of units supplied or demanded will be given by qx100. The supply when T-shirts are $5 is units. (Round to the nearest whole number as needed.)
