Kim paid 3/7 of a bill, Sherri paid 35% of the bill, and Judy paid the rest.

Which of the following statements is true?

A. Kim paid the most.

B. Sherri paid the most.

C. Judy paid the most.

D. They all paid the same amount.

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
