Problem of the Week

Key points:

• Willy competes in 10 events
• On the first five events his average is 6.8
• On the next three events, his average is 7.2
• What must Willy score on his last two rounds to have exactly 75 points?

Solution:

6.8 x 5 = 34

7.2 x 3 = 21.6

34 + 21.6 = 55.6

75 - 55.6 = 19.4

19.4 / 2 = 9.7

34 + 21.6 + 19.4 = 75

Therefore, Willy has to score 9.7 for the next two rounds to get a total score of 75.
