I think for the second question, it's compound interest.
Hi
alright problem #1
If a question gives you the MC (marginal cost) function c'(q), and asks you to find the cost to increase production from a to b units, then is it simply c'(b) - c' (a)? or do we need to know the TC (Total cost) function for this?
problem #2
If and investment increases by 500% over a 15 year period under a constant periodic interest rate of r% monthly, the annual interest rate is approximately...
a) 10.78 %
b) 11.32 %
c) 12.69 %
d) 12.00 %
Um, so here i am not sure whether this question is pertaining to interest compounded continuously or compound interest.
