The answer is A. Kim paid the most.

x - the total amount
k - Kim's amount
s - Sherri's amount
j - Judy's amount

k + s + j = x
k = 3/7 x = 0.43 x
s = 35%x = 0.35x
j = x - k - s = x - 0.43x - 0.35 x = x - 0.78x = 0.22x

So:
0.43x > 0.35x > 0.22x
    k     >     s    >    j

Answer:

A is the correct option.

Step-by-step explanation:

Let the total amount of the bill is x

Hence. amount paid by Kim is \(\frac{3}{7}x=0.429x\)

Amount paid by Sherri is \(35\% \text{ of } x=0.35x\)

And the amount paid by Judy is  \(x-0.429x-0.35x=0.221x\)

Now, we can see that

0.429x > 0.35x > 0.221x

Hence, we can conclude that Kim paid the most.

A is the correct option.
