Eight bottles of water are shared equally among three people, and each person gets 8/3.

8/3 of point C shall be paid to 4.8 yuan. It can be calculated that the price of a bottle of water is: 4.8/(8/3)=4.8*(3/8)= 1.8 (yuan).

A paid for five bottles of water, that is, 1.8*5=9 (yuan).

B paid for 3 bottles of water, that is, 1.8*3=5.4 yuan.

So A can be taken back: 9-4.8=4.2 yuan.

B Recoverable: 5.4-4.8=0.6 yuan.

I hope it helps you ~
