Melissa used to work as a hostess at one of the tony restaurants near Central Park where she was making approximately $1,200 a week. Her employer had to let her go in March after the lockdown. She filed for unemployment and started getting $600 per week from the government. She didn't want to dip into her savings to support her through this pandemic and decided to start living more frugally with just $600 per week. Describe how Melissa's demand for any good varies between February and April. Provide appropriate diagrams.
