5 70 _________ _________
3 50 _________ _________

Answer 1

Elasticity of supply schedule

Computation

The elasticity in supply is computed as follows:

E_s = $ΔQ/Q/Δ P/P$

The change in price and change in quantity supplied is given by:

Elasticity = (Q₂ – Q₁)/Q / (P₂ - P₁)/P

Explanation

A 18%, 22%, 29% and 40% decrease in price leads to a respective decrease in the quantity supplied by 15%, 18%, 22% and 29%. This results to an elasticity coefficient of 0.85, 0.82 0.78 and 0.71 respectively. Since the elasticity of supply is less than 1, it is hence inelastic. The implication is that the supply is price inelastic implying that that sellers respond weakly to price changes.
