Answer:
32 bottles
Step-by-step explanation:
In this scenario, we have to divide 8 by 1/4 to see how many of those 1/4-liter bottles can be filled with 8 liters of water. So, let's go ahead and see how this looks mathematically, then we'll start simplifying:
÷ 
Dividing by a fraction is the same as <em>multiplying by that same fraction's reciprocal</em>, so we can rearrange our math to make things easier.
× 
Now, we can multiply the numerators and the denominators.
×

So 32 of those 1/4 liter bottles can be filled from a jug containing 8 liters of water. Hopefully this was helpful! If anything was confusing or didn't make sense, let me know so I can make things clearer. :)
The correct answer should be approximately letter b) 16x+32y=144 x+y=7
