a.

b.
The juice in the plastic bottle is 1 cent cheaper per ounce.
c.
The juice in the glass bottle is 10 cents cheaper per ounce.
d.
The juice in the plastic bottle is 10 cents cheaper per ounce.

Answer 1

B

Explanation:

B is correct

Answer 2

The answer is letter b.

$4.20 / 60 ounce is the rate for the glass bottle while $3.06 / 51 ounces is the rate for the plastic one.

Simplified, the glass bottle is $0.07 / ounce while the plastic bottle is $0.06 / ounce.

Ergo, the plastic bottle is cheaper by a cent per ounce.
