Check my work please? Use the compound interest formula. given three of the quantities, A, P, r and t, find the remaining one. question: If you invest 7400 for 5 years which will return more money : an interest rate of 5% compounded quarterly or an interest rate of 4.8% compounded continuously. For the first one I got $7874.21 and for the second one I got 7407.24 concluding that the second investment will return the most money. Is this correct?

I did the first part of the problem again: If you invest 7400 for 5 years which will return more money : an interest rate of 5% compounded quarterly. That's why used 5. I'll do the second part again now.
