I have attached screen shots of two questions, 14-19 and 14-25.
1) Complete: Chapter 14, p. 566 – Complete Problem 14-19.
Chapter 14, p. 567 – Complete Problem 14-25.
2) Use one Excel spreadsheet file for the calculations and explanations, with one worksheet per problem. Use the problem number for each worksheet name. Cells should contain the formulas (i.e., if a formula was used to calculate the entry in that cell).
