C) 24 bottles for $3 by 75¢ per bottle
D) 36 bottles for $4 by 1.4¢ per bottle

Respuesta :

i would say 36 bottles for $4 by 1.4 cent because you get more bottle of waters and it doesn't cost that much money for a bottle of water

Answer:

The better buy is option C because you will be paying $3 instead of $18 for 24 bottles. Which means you will save $1.2 more than option B and $15 in total.

Step-by-step explanation:

Option A:

If the bottle is 1.5 cent per bottle and you buy 24 bottles you will only spend:

[tex]=0.015*24=0.36[/tex] therefore only 36 cent.

Option B:

If the bottle is 70 cent per bottle and you buy 24 bottles you will only spend:

[tex]=0.70*24=16.8[/tex] therefore you will pay $16.8.

Option C:

If the bottle is 75 cent per bottle and you buy 24 bottles you will only spend:

[tex]=0.75*24=18[/tex] therefore you will pay $18.

Option D:

If the bottle is 1.4 cent per bottle and you buy 36 bottles you will only spend:

[tex]=0.014*36=0.50[/tex] therefore you will pay 50 cent.

∴ Option A you will overspend $3-0.36cents = $2.64

∴ Option B you will save $16.8-$3 = $13.8

∴ Option C you will save $18-$3 = $15

∴ Option B you will overspend $3-$0.5 = $2.5

Therefore option C is the best option because you will be paying $3 instead of $18 for 24 bottles. You will save $1.2 more than option B.
