Acompany needs to package 2,400 pencils. a box in the shape of a rectangular prism can hold 60 pencils. a cylindrical container can hold 80 pencils. each box costs the company $0.50, while each cylindrical container costs $0.75.

which packaging should the company use to minimize cost? explain.

a. the rectangular prism boxes should be used because they will cost the company $2.50 less than using the cylindrical containers.

b. the cylindrical containers should be used because they will cost the company $2.50 less than using the rectangular boxes.

c.the rectangular prism boxes should be used because they will cost the company $5.00 less than using the cylindrical containers.

d. the cylindrical containers should be used because they will cost the company $5.00 less than using the rectangular boxes.

Each rectangular prism box costs the company $0.50, while each cylindrical container costs $0.75. You have to count how many boxes or cylindrical containers the company should buy and what is the total cost in each case.

1. 2,400 : 60 = 40 - the amount of rectangular prism boxes that can contain 2,400 pencils.

$0.50 · 40 = $20 - the total cost if packing in boxes.

2. 2,400 : 80 = 30 - the number of cylindrical containers that can contain 2,400 pencils.

$0.75 · 30 = $22.50 -  the total cost if packing in containers.

Therefore, $20 < $22.50 and the difference is $2.50.

choice A - The rectangular prism boxes should be used because they will cost the company $2.50 less than using the cylindrical containers.

1) on the number line, -1.5 can be seen as going backwards 1.5.
there are -4 groups of -1.5
this means that you have to move in the opposite direction that you would normally move 1.5
4 groups of 1.5 is 6 (because you have to move in the positive direction)
6 is the answer

2) 975 feet below the surface
