note on showing work:
question 1: use linear regression on calculator or computer to find line of best fit
question 2: use a calculator or computer to solve the resulting equation to find YTM (as in previous assignment HW5)
question 3: you may use a calculator or computer to solve the system of equations to find the “RREF” form
question 4: there is a formula in assignments HW16 through HW20 that computes future value with repeated payments and interest, set up formula and use calculator to answer
question 5: there are formulas for overall percent change and compound growth (example – HW16), set up formula and then use calculator as needed
