Who knows financial math

What type of "financial" math are we talking about? If it is accounting related I may be able to help.
 
its fucking gay is what it is.

anybody know the rate of interest for money to triple in 3 years?

or

if an investment of 972 earned interest of 763 at 3.6 percent compounded semi anually. how many years was it invested
 
Not sure if you got taught this, but for the first one you can use the rule of 72
72/rate of return= years to double
so 24%
 
so again, i would use the same equation but with an extra piece: a=p(1+(r/n))^t*n

so plug in 972 for p, .036 for r, 763+972 for a, 2 for n because its compounded semi annually, and solve for t
 
im so pumped on all you guys being so helpful. if you ever find yourself in central ontario i owe you a double cheeseburger.
 
is he letting you use the TVM solver on your calculator?

because i dont do these questions without using that anymore

but yeah, just plug everything into your simple interest equation and solve for N...

also, if you know about the rule of 72 for doubling rate... the rule of 110 is for tripling rates...

im a shitty student of business math but i hope that helps you my son!
 
yeah i was gonna ask too, if you can use a financial calculator to enter cash flows and find the time value of money then you should be set that way. but if not doing it by hand is more of a pain.
