Hi there,
John:
650 + 11x150 = $2300 in a year
Lawrence:
2.35 + 4.70+ 9.40 + 18.80 + 37.40 + 74.80 + 149.6
+ 299.2 + 598.4 + 1196.8 + 2393.6 + 4787.2
= $9572.25 in a year
..........................
1 1/2 years
John:
650 + 17 x 150 = $3200 in 1 1/2 years
Lawrence:
$9572.25 + 9574.4 + 19148.8 + 38297.6
+ 76595.2 + 153190.4 + 306380.8
= $612759.45 in 1 1/2 years

Hope this helps:-)
