The demand for a product is upper q superscript d baseline equals 100 minus 4 upper p plus 3 upper p subscript upper x and supply is upper q superscript s baseline equals 10 plus 2 upper p? , where q is the quantity of the product in thousands of? units, p is the price of the? product, and upper p subscript upper x is the price of another good. when upper p subscript upper x ? = $40, the equilibrium price of the product is ? $ nothing and the equilibrium quantity is nothing thousand your responses as whole? numbers.) at the equilibrium price and? quantity, the price elasticity of demand for the product is nothing. ? (enter your answer as a real number rounded to 2 decimal places. ? don't forget a negative sign if? appropriate.) demand is ? unit elastic price inelastic price elastic . at the equilibrium price and? quantity, the price elasticity of supply for the product is nothing. ? (enter your answer as a real number rounded to 2 decimal places. ? don't forget a negative sign if? appropriate.) the cross price elasticity of demand for the product at the equilibrium point is nothing. ? (enter your answer as a real number rounded to 2 decimal places. ? don't forget a negative sign if? appropriate.) the product and good x are ? substitutes complements .
