Answer:

a) cross price elasticity = {(QJ2 - QJ1) / [(QJ2 + QJ1)/2]} / {(PB2 - PB1) / [(PB2 + PB1)/2]}

cross price elasticity = {(15 - 20) / [(15 + 20)/2]} / {(3 - 2) / [(3 + 2)/2]} = (-5/17.5) / (1/2.5) = -0.71 complements

b) cross price elasticity = {(QJ2 - QJ1) / [(QJ2 + QJ1)/2]} / {(PB2 - PB1) / [(PB2 + PB1)/2]}

cross price elasticity = {(20 - 15) / [(20 + 15)/2]} / {(3 - 2) / [(3 + 2)/2]} = (5/17.5) / (1/2.5) = 0.71 substitutes
