Claire has a small personal business making scented candles. her startup costs are $200. her cost to make each candle is $1.50. she sells each candle for $4.00. write the cost function of producing x candles.

Step-by-step explanation:

If we assume A = the amount of candles she produces and sells then we can assume this equation.

(4.00×A) - ((A×1.50)+200)

The first part is calculating how much Claire makes at first with her candles being sold while taking account of the amoubt of candles and the cost for making one.

The second part is for the Amount of candles and the cost of starting and the cost of each candle and that amount is the amount Claire will lose and subtracted by the first amount.

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".
