Future value for single cash flow

Looking for some serious help in Financial Management assignment. I needed honest and willing to meet my dead line. Instruction as following questions using grammatically correct language and appropriate APA citations. All questions need to be answer and with APA citations. All material MUST come from the book only. (The book that used is Finance by Cornett, Adair, & Nofsinger, 2016). Chapter 4 Time Value of Money 1: Analyzing Single Case Flows Page 78-99, and Chapter 5 Time Value of Money 2: Analyzing Annuity Flows, pages 100-127. There are some hints and suggestions for certain questions in this assignment.

Answer the following questions and complete the following problems, as applicable. Unless otherwise directed, assume annual compounding periods in computational problems. You may solve the following problems algebraically, or you may use a financial calculator or Excel spreadsheet. If you choose to solve the problems algebraically, be sure to show your computations. If you use a financial calculator, show your input values. If you use an Excel spreadsheet, show your input values and formulas.

Note: In addition to your solution to each computational problem, you must show the supporting work leading to your solution to receive credit for your answer.
