Section 2.2 (85)

In August 2013, E*TRADE Financial was offering only 0.05% interest on its online checking accounts, with interest reinvested monthly. Find the associated exponential model for the value of a \$5000 deposit after "t" years. Assuming that this rate of return continued for 7 years, how much would a deposit of \$5000 in August 2013 be worth in August 2020? (Answer to the nearest \$1 .)

Step 1

Step 2

Also, it is given that the interest is compounded monthly. As there are 12 months in a years, n = 12. The required exponential model is evaluated as follows.

Step 3

Since the rate of return is continued for 7 years, substitu...
