Question

water cost $2 for 8 bottles orange juice cost a $1.50 for 3 bottles which is more expensive per bottle ​

Answer 1

I believe you can use ratios and multiply both of them like fractions to get the same amount of bottles and compare the prices fairly.


2:8 = 2/8
1.5:3 = 1.5/3


(2/8)3 = 6/24 or $6 per 24 bottles
(1.5/3)8 = 12/24 or $12 per 24 bottles


In conclusion, the latter ($1.50 for 3) costs more than the $2 per 8.

Answer 2

orange juice

Explanation:

1 water -> 2÷8

= 0.25

1 orange juice ->1.50 ÷ 3

= 0.50

hence, orange juice is more expensive
