use the compound interest formula a=p(1+0) to find the annual interest rate, r. if in 2 years an investment of $4,000 gros to $4,840.
the rate is
%.
teh

  10%

Step-by-step explanation:

The appropriate formula for the future value of an account with compound interest is ...

  A = P(1 +r)^t

where r is the annual rate, and t is the number of years.

Fill in the given values and solve for r:

  4840 = 4000(1 +r)^2

  4840/4000 = (1 +r)^2

  √1.21 = 1 +r

  1.1 = 1 +r

  r = 1.1 -1 = 0.10

  r = 10%

The rate is 10%.
