I just did the assignment, and those were the correct answers.

Answer 2

Answer: Rectangular container is preferred to minimize the costs and  there are 142 rectangular container is needed to pack 6400 candles.

Explanation:

Since we have given that

Number of candles in a rectangular container = 45

Number of candles in a cylindrical container = 41

Cost of each rectangular container = $15

Cost of each cylinder container = $16

That means ,

In case of rectangular container,

Cost of 45 candles = $15

Cost of 1 candle is given by

$\frac{15}{45}=\frac{1}{3}=\ 0.33$

Similarly,

In case of cylindrical container,

Cost of 41 candles = $16

Cost of 1 candle is given by

$\frac{16}{41}=\ 0.39$

So, if the company needs to package 6,400 candles , it should use rectangular containers to minimize costs.

Number of candle he need to pack = 6400

Number of rectangular container for 6400 candles is given by

$\frac{6400}{45}=142.2=142\ approximately.$

Hence, there are 142 rectangular container is needed to pack 6400 candles.
