Use thecompound-interest formula:

. . . . .

...where the variables are as explained in the link above. For this particular exercise, r = 0.06 and n = 4. You aren't given an initial value or desired final value, but you are provided with a relationship between the two: A = 2P. So you need to solve:

. . . . .

...for the value of "t". You'll need to use logs tosolve this exponential equation.

I'm not sure what is meant in the second part of this exercise. It sounds as though the interest term is one day, rather than one year with daily compounding...?

What formula(s) have they given you for this? How far have you gotten in the application of this/them?

Please be complete. Thank you!
