Answer:

Dale would reach his goal with an annual interest rate of 6.18%.

Step-by-step explanation:

For compounding continuously, recall the following equation:

[tex]A = P(e)^{rt}[/tex]

A = final amount ($4200)

P = principal amount ($2000)

r = rate (unknown)

t = time (12 years).

You'll have to use natural logs for these types of questions. Remember that ln (e) = 1.
