1 answer:

8 0

The answer is (3) 4896.

This number comes from multiplying 18 x 17 x 16

This is because any of the 18 students could be picked as a leader. Then, any of the remaining 17 students could be picked as a recorder. Then, any of the remaining 16 students could be picked as a timekeeper. Therefore, you multiply 18 by 17 by 16 to get 4896 combinations.

Paul, Colin and Brian are waiters.

Kisachek [45]

Add the ratios together: 2 + 3 +4 = 9

Divide the total tips by 9:

77.40 / 9 = 8.60

Multiply each portion of the ratio by 8.60:

2 x 8.60 = 17.20

3 x 8.60 = 25.80

4 x 8.60 = 34.40

The ratios are in order of the people:

Paul got 17.20

Colin got 25.80

Brian got 34.40

Brian got 34.40 - 17.20 = 17.20 more than Paul
