The lowest weekly wage that the financial firm can spend in order to hire five human resource specialists is____.
Suppose the hiring director of the financial firm prefers taller candidates because they think it will increase revenue, and so they impose a requirement that all newly hired human resource specialists must have a height of at least 67 inches. With this mandate in place, the weekly wage rate the financial firm now must pay in order to hire five human resource specialists increases by_____.

Suppose that a power plant dumps byproducts into a nearby river, creating a negative externality for those living downstream from the plant. Producing additional electricity imposes a constant per-unit external cost of $490. The following graph shows the demand (private value) curve and the supply (private cost) curve for electricity. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $490 per unit.
