Problem
Mitch cares only about how much he can write. Because a pen will write 7 miles of text and a pencil will write 35 miles of text, Mitch considers them perfect 5-to-1 substitutes. If the price of pens is given by Ppen and the price of pencils is given by Ppencil , and if Mitch's income is given by Y, use indifference curve analysis to derive the demand curve for pencils.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
