Question

If whitney purchased a soccer ball for $40 when she was willing to pay $50 for the soccer ball, her consumer surplus would be? a. $0 b. $10 c. $40 d. $50 e. $90

Answer 1

b. $10

Explanation:

She was willing to pay $50, which would've then been gone, but she'd have had a new soccer ball.

But when she got to the store maybe they were on sale for $40. Now $40 is gone, she has a new soccer ball, AND she still has $10 in her pocket that she brought with her to buy it.

Sounds like a "consumer surplus" to me.
