Question

You are making candles for your friends. A mold for the candles costs $22.50 and wax to make one candle costs $5. Write an algebraic expression for the total cost of making x candles. You make 8 candles. Find the total cost

Answer 1

The total cost of making x candles can be found using the expression 22.50 + 5x. If 8 candles are made, the total cost is $62.50.

Step-by-step explanation:

To find the total cost of making x candles, we need to consider the cost of the mold and the cost of the wax for each candle. The cost of the mold for one candle is $22.50, and the cost of the wax for one candle is $5. Therefore, the algebraic expression for the total cost of making x candles is 22.50 + 5x.

In this case, you are making 8 candles, so we can substitute x with 8 in the expression. Therefore, the total cost is 22.50 + 5(8) = 22.50 + 40 = $62.50.

Answer 2

`y=27.5\cdot{x}`

$220

Step-by-step explanation:

If x represents the amount of candles to be made, we can write the expression relating the total cost to make x candles by using the cost of the mold and wax. We know that for one candle, the mold it costs $22.50 and wax costs $5. Therefore:

`=22.5+5=27.5`

Let y be the total cost of to make x candles:

`y=27.5\cdot{x}`

For 8 candles x=8:

`[tex]y=27.5\cdot{8}`=220[/tex]

It will cost $220 to make 8 candles.
