The total daily cost (in dollars) of manufacturing scented candles is given by the function c(b) = 250 + 3b, where b is the number of candles manufactured. which function represents the average manufacturing cost, a, in terms of b? a. a(b)= b/250 + 3b b. a(b)=250 + 3b/b c. a(b)=(250 + 3b) x (b) d. a(b)=250 + 4b

Average cost is the ratio of total cost and the number of goods. Hence, for this problem:

Average cost=

So,

Where A(b)= average cost, c(b)= total cost and b= number of candles.

Since, c(b)=250+3b

So, the average cost is

the answer is d. 75%

investment b is an ordinary annuity with $3,909.64 in the account after one year.
