Adrienne and Stephen consume pizza, Z, and cola, C. Adrienne's utility function is and Stephen's is UA=ZACA Us= (Zs) 0.5 (Cs) 0.5 Their endowments are ZA = 14, CA = 40, Zg = 6, and Cg = 80. What are the competitive equilibrium prices, where one price is normalized to equal one? Determine p, the competitive price of Z, where the price of C is normalized to equal one. The competitive price, p, is $. (Enter your response rounded to two decimal places.)
