((150-130)/140) / ((5-4)/4.5) = 0.6429 c) Yes, as price decrease, numbers increase, displaying inelastic properties. Therefore, the total expenditure decreases as well. d) The total expenditure is at a maximum when the price is \$6. Video stores

This is because the price change remains the same and the change in quantity is of same proportion. Therefore, the proportion of change in quantity demanded to change in price remains the same. f) ((210-190)/200) / ((7-6)/6.5) = 0.65 The elasticity of demand for the price change of \$7 to \$6 is now less than before. This is due to the fact that the quantity demanded has increase as before, but in a significantly smaller interval.
