In her spare time, Kathy babysits her neighbors' kids for extra income. Her neighbors will pay her \$15 per hour. Kathy is willing to babysit for the first hour for \$5, the second hour for \$7, the third hour for \$10, the fourth hour for \$14, the fifth hour for \$18, the sixth hour for \$25.

As Kathy is rational, so she will babysit for first four hours. Her producer surplus = (15 - 5) + (15 - 7) + (15 - 10) + (15 - 14) = 10 + 8 + 5 + 1 = \$24

The price will increase, and producer surplus will increase.
(Due to new medical research, demand for orange juice will increase which will increase the price and quantity sold of orange juice so producer surplus will increase.)
