Elasticity of Supply Determines Quantity Response

Steps:

• Calculate % change in price: ($2.50 -$2.00) / $2.00 = 0.25 or 25%.
• For short run, % change in quantity supplied = elasticity × % change in price = 0.8 × 25% = 20%; increase = 20% × 1000 = 200 units.
• For long run, % change in quantity supplied = 1.4 × 25% = 35%; increase = 35% × 1000 = 350 units.
• The question asks for increases in both periods, yielding 200 (short run) and 350 (long run).

Not enough information: Choices provide single numbers, but question requires two values; no option matches 200 and 350.

Final answer: Not enough information.
