1.425 gallons of apple juice are in one container
I got this because if she starts with 6 gallons and she’s left with 0.3 gallons, you would need to subtract 6 by 0.3 (6-0.3=5.7). So now you know how much is in 4 bottles. Now you need divide 5.7 by 4 to find out how much is in each container (which is 1.425).
-15s+45=23
-15s+45-45=23-45
-15/-15s=-22/-15
s=22/15

Hoped this helps! Just had it on a quiz and got it right. If you have boxex by 4 a^1 b^2
