[(Q2 - Q1) / (Q1 + Q2)] / [(P2 - P1) / (P1 + P2)]
[(Q2 - Q1) / (Q1 + Q2)] * [(P2 - P1) / (P1 + P2)]
[(Q2 - Q1) * (P1 + P2)] / [(Q1 + Q2) * (P2 - P1)]
[(Q2 - Q1) * (P1 + P2)] * [(Q1 + Q2) * (P2 - P1)]

20. How does the law of diminishing marginal utility relate to the elasticity of demand?
It increases the elasticity of demand.
It decreases the elasticity of demand.
It has no impact on elasticity.
It only affects the price elasticity of supply.
#23
22. If the cross-price elasticity of demand is negative, what can be inferred about the goods?
They are complementary goods.
They are substitute goods.
