Post by: simba on November 05, 2012, 05:35:05 pm: Just wondering what answer people got for this? I think I might have it wrong :(

Post by: StumbleBum on November 05, 2012, 05:39:23 pm: i believe all you needed was $40000(1.0065)^{12}$ (or something equivalent), and then just to amke sure i showed that it did indeed equal the answer they required.

Post by: StumbleBum on November 05, 2012, 05:45:35 pm: Oh, yeh well im guessing you probably used 40000 as the primary value instead of 43234, which was what you had to use because it said "after the first 12 months" which was what we just had to show obtained 43234.

Post by: J0nnyb0i27 on November 05, 2012, 07:37:55 pm: For 3.c)i), could you put the table of values from TVM solver to demonstrate how you could get the answer? That's still calculation isn't it? It didn't explicitly say use the formula.
