Rachel deposited $5,960.32 into a savings account with an interest rate of 4.2% compounded twice a year. About how long will it

ahrayia [7]

You need the compound interest formula solved for time:
Years = log (total / principal) / n * log (1 + rate / n)
Years = log (9,000 / 5,960.32) / 2 * log (1 + .042/2)
Years = log ( 1.509986041) / 2 * log (1.021)
Years = 0.1789729325 / 2 * 0.0090257420869
Years = 0.1789729325 / 0.0180514842 
Years = 9.9145826746 
the answer is "d"
