Answer:
Option (b) is correct.
Step-by-step explanation:
At selling price = $1 and No. of units sold = 75 cookies,
Total revenue = selling price × No. of units sold
= $1 × 75 cookies
= $75
At selling price = $0.50 and No. of units sold = 200 cookies,
Total revenue = selling price × No. of units sold
= $0.50 × 200 cookies
= $100
Therefore, there is a rise in the total revenue from $75 to $100 and hence, price elasticity of demand for sugar cookies is elastic.
