1. Valen
2. Fabian
3. Bobby
4. Jenson

(a)
Total score of Fabian and Bobby
= 79 x 2
= 158

Total score of Bobby and Valen

= 77.4

(c)
Bobby's score
= 141.6 - 61
= 80.6

(d)
Total score of Jenson and Valen
= 67 x 2
= 134

Jenson's score
= 134 - 61
= 73

Answer(s): (a) 61; (b) 77.4; (c) 80.6; (d) 73
