Here's my question:
$541.39(1+i) Can you please show me how to do this? grade 12 Rich Bolton Hi Rich, I expect that you want to find i. To isolate i on the left side of the equation you can divide both sides by 542.39 to get
^{15} = 784.09/542.39Now take the log of both sides to get
^{15}) = log(784.09/542.39)The reason for using the logarithm here is that
^{15}) = 15 log(1+i)and hence the equation can be written
Can you complete the problem now? Penny |
