Thread: random homework quesstion, i am stuck

no

This is what i did > Before using this someone should confirm this answer there mite be mathematical error , but i am 75 % sure this is right.

20,000,000 pastes are made /year
pallet = 75 lb
2 uses for each pallet
10 $ for a pallet
37.50 $ for getting rid of one pallet (75 lb * $.50)
dimension of pallet 48 x 48 x 40
25/pallet for service

first toothpaste dimension

2.5 x 2.5 x 6

2.5 x 2.5 x 2 = 12.5 in ^2 >>>> 2 is number of sides
2.5 x 6 x 4 = 60in ^ 2 >>>> 4 is number of sides
12.5 + 60 = 72.5 in^2
.001 x 72.5= $0.0725
0.0725 x 20 000 000 = $1 450 000 material cost
2.5 x 2.5 x 6 = 37.5 in ^3
48 x 48 x 40 = 92160 in ^ 3
92160/ 37.5= 2457.6 thats how many tooth pastes can fit on one pallet since you cant have fraction u must round down.
2457 toothpastes on one pallet
20 000 000 / 2457 = 8140.008 lets just say 8140 pallets to transport
20 000 000
8140 pallets and since its 2 pallets are reused
8140 /2 = 4070 pallets needed
4070 x $10 = $40700 to buy pallets
4070 x $37.5 = $152325 to dispose
8140 x 25 = $203500 to transport

1450 000+40700+152325+203500 =$1 846 825

If you do the same math using the new dimensions you get
dimension 2.25 x 2.25 x 5.75
$1 237 500 material
$ 31 600 buying pallets
$ 118 500 disposing
$ 158 000 Service

= $ 1 545 600 + 100 000 for making changes = 1 645 600 this is only first year second year continues at $1 545 600.

1 846 825-1 545 600= 301225 thats the amount they will save a year in total a year.
100 000/ 301225= 0.3319777 how long it will take in one year for them to get back on track
so about 1/3 of the year for them to recover from the 100 000 dollar defficet
