i'm stuck on question 16 and 17

16. Two investors, Brent and Lincoln, invest different amounts of money at the same time for an 8-year period. Brent invests $10 000 at 6% per year and his final amount is given by the formula A = 10000(1.06 )8. Lincoln is shrewder, and was able to invest only $8000 and end up with the same amount at the end. His final amount can be modelled using the equation A = 8000(1+ i )8. Determine the value of i for Lincoln and the yearly interest rate his money earned to allow this to happen. (5 marks) 17. In many cases, a worker's hourly wage depends on the number of hours worked. If a certain number of hours is reached. the pay rate beyond that point increases. When working beyond a certain number of hours, some employees earn time-and-a- taif. or 1.5 times their reqular pay, for the remaining hours.
