Answer:
$7.5
Greater
Explanation:
Price elasticity of demand = percentage change in quantity demanded/ percentage change in price
0.2 = 10%/ percentage change in price
percentage change in quantity demanded = 50% = 0.5
0.5 = (New price - $5) / $5
New price = (5 × 0.5) + 5 = $7.5
In the short run, demand is relatively inelastic because consumers need time to find suitable substitutes but in the long run, demand is usually more elastic.
