in first x games martin scored 32x scores. in last 14. so total average:
(32x+14)/(x+1) = 30
32x+14=30x+30
2x = 16
x=8
so in total number of games was 8 + 1 = 9
answer B

\(32x + 14 = 30 (x + 1 )\)
Or, \(32x + 14 = 30x + 30\)
Or, \(2x = 16\)
So, \(x = 8\)
Hence, total Number of games played is 8 + 1 = 9
Answer will be (B) 9
