The average number of points scored by Caden, Glen and Gabriel was 72. The average number of points scored by Lee and Gabriel was 69. How many points did each of them score?

1. Gabriel
2. Caden
3. Glen
4. Lee

(a)
Total score of Caden and Glen
= 76 x 2
= 152

Total score of Glen and Gabriel
= 71.5 x 2
= 143

Total score of Caden, Glen and Gabriel
= 72 x 3
= 216

Gabriel's score
= 216 - 152
= 64

(b)
Caden's score
= 216 - 143
= 73

(c)
Glen's score

= 79

(d)
Total score of Lee and Gabriel
= 69 x 2
= 138

Lee's score
= 138 - 64
= 74

Answer(s): (a) 64; (b) 73; (c) 79; (d) 74
