Calc. Help ASAP please
posted by Joe .
the tuition at a college increases exponentially. the current tuition (let it be t=0) is 36,000 and in 2 years it will be 39,690.
a) find a formula to predict the cost of tuition in t years.
Is this right? And I'm stuck at the end.
2.400=kt ??? Don't know what to do from here.
b) what is the yearly growth rate of tuition (in %)?
c)what will the tuition be in 25 years?
for this part, I think I plug 25 in for t of the formula I have not figured out in part a????
Please help! Test soon.
when t=2 y= 39690, so 39690=3600e^k(2)
