$30
36
300 shares x $0.15
$45
300 x 0.10 = 30
Add an extra 1/2 of 30
30 x 1/2 = 15
30 + 15 = 45
37
400 shares x $0.15
$60
400 x 0.10 = 40
40/2 = 20
40 + 20 = 60
38
500 shares x $0.15
$75
500 x 0.10 = 50
500 x 0.05 = 25
50 + 25 = 75
39
600 shares x $0.15
$90
600 x 0.10 = 60
600 x 0.05 = 30
60 + 30 = 90

1,000 x $0.15
$150
1,000 x 15 = 15,000
Add in the decimal point = 150.00
44
1,500 shares x $0.15
$225
1,500 x 0.10 = 150
1,500 x 0.05
Bump decimal left one digit on BOTH sides
150.0 x 0.5 = 75
150 + 75 = 225
45
2,000 shares x $0.15
$300
2,000 x 0.10 = 200
2,000 x 0.05
Bump decimal left one digit on BOTH sides
200.0 x 0.50 = 100
200 + 100 = 300
46
2,500 shares x $0.15
$375
2,500 x 0.10 = 250
2,500 x 0.05
Bump decimal left one digit on BOTH numbers
250.0 x 0.50 = 125
Same as 250/2 = 125
250 + 125 = 375
47
3,000 shares x $0.15
$450
3,000 x 0.10 = 300
3,000 x 0.05
Bump decimal left one digit on BOTH numbers
300.0 x 0.5 = 150
Same as 300/2 = 150
300 + 150 = 450
48
3,500 x $0.15
$525
3,500 x 0.10 = 350
Break up 3,500 into 2 easy parts (3,000 and 500)
3,000 x 0.05
500 x 0.05
Move decimal left one digit on BOTH numbers
300 x 0.5 = 150
50 x 0.5 = 25
150 + 25 = 175
175 + 350 = 525
49
4,000 shares x $0.15
$600
4,000 x 10 = 40,000
4,000 x 5 = 20,000
40,000 + 20,000 = 60,000
Convert back to dollars
60,000/100 = 600
50
4,500 shares x $0.15
$675
4,500 x 0.10
Move decimal left one digit on BOTH numbers
450 x 1 = 450
4,500 x 0.05
Move decimal left TWICE on BOTH numbers
45 x 5 = 225
450 + 225 = 675
