Can someone help me solve this please?? it might b a little hard to see. thank you!!

Imogene invested $8,000 in a bank account that pays 8 percent simple interest at the end of each year. her friend invested the same amount in stocks where the growth of the investment is represented as 2,000 times the square root of 2 less than the time lapsed in years. if y1 and y2 represent the amount earned in dollars and t is the time lapsed in years, which system of equations correctly represents the situation?

If olu is twice as old as funmi if the sum of their ages is 60 how old is olu

I’m stuck on this equation, anyone got the answer?
