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.
