Target sells 24 bottles of water for $3, and 36 bottles of water for $4. Which is the better buy and by how much?
pishuonlain [190]

Answer:

D) 36 bottles for $4 by 1.4¢ per bottle

Step-by-step explanation:

We calculate bottle per dollar for each option.

#A

Bottles/Dollar=\frac{24\ bottles}{\$3}=8 bottles/dollar

#Both B and C charges the same as A and will have bottle/dollar ration of 8:1

#D

=\frac{36}{4}\\\\=9

Hence, D is the better buy  as it gives you 9bottles per $1 spent as compared to the 8 bottles per $1 spent as in the other 3 options.
