1. Zoe is trying to decide how to divide her time between her job as a wedding photographer, which pays $27 per hour for as many hours as she chooses to work, and as a fossil collector, in which her pay depends on both the price of fossils and the number of them she finds. Earnings aside, Zoe is indifferent between the two tasks, and the number of fossils she can find depends on the number of hours a day she searches, as shown in the table below:

a. Derive a table with price in dollar increments from $0 to $30 in the first column and the quantity of fossils Zoe is willing to supply per day at that price in the second.

b. Plot these points in a graph with price on the vertical axis and quantity per day on the horizontal. What is this curve called?
