Answer 2

Answer: First option is correct.

Explanation:

Since we have given that

$12.60 for 7 bottles of juice.

then, cost of each bottle of juice would be

`(12.60)/(7)=\$1.8`

$10.98 for 6 bottles of juice.

then, cost of each bottle of juice would be

`(10.98)/(6)=\$1.83`

$18.10 for 10 bottles of juice.

then, cost of each bottle of juice would be

`(18.10)/(10)=\$1.81`

$16.38 for 9 bottles of juice.

then, cost of each bottle of juice would be

`(16.38)/(9)=\$1.82`

Hence, $12.60 for 7 bottles of juice is the best buy as it is the cheapest one.

Therefore, First option is correct.
