Thomas is not too bright. He wants to have $5,000 saved up in 6 years so that he can surprise his parents with a luxurious vacation for their 50th wedding anniversary. If he invests $1,000 today as a lump sum in a bank account that compounds interest quarterly, what annual interest rate will he need in order to achieve his goal?
