1. 3 year(s) ago, Goran invested 32,251 dollars. He has earned and will earn 8.54 percent per year in compound interest. If Sarah invests 49,680 dollars in 3 year(s) from today and earns simple interest, then how much simple interest per year must Sarah earn to have the same amount of money in 8 years from today as Goran will have in 8 years from today? Answer as a rate in decimal format so that 12.34% would be entered as .1234 and 0.98% would be entered as .0098.

2 year(s) ago, Fatima invested 6,210 dollars. In 2 year(s) from today, she expects to have 7,520 dollars. If Fatima expects to earn the same annual return after 2 year(s) from today as the annual rate implied from the past and expected values given in the problem, then in how many years from today does she expect to have exactly 10,350 dollars? Round your answer to 2 decimal places (for example, 2.89, 14.70, or 6.00).
