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?

answer

the answer is b:

  a(b) = (250+3b)/b

explanation

the average cost is found by dividing the total cost with the number of candles manufactured.

the total cost = 250 + 3b

number of candles = b

a(b) = (250 + 3b) ÷ b

a(b) = (250 + 3b)/b

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
