Well lets first round the 129.99 up to a flat dollar (cash registers will already do this).
Step 1: Rounding 129.99 up to 130.00
Step 2: Now lets convert 40% to a decimal. Move the point two places to the left.
Step 2: 40% = 4.0 (Moved one place to left)
Step 2: 40% = .40 (Moved two places to left)
Step 3: Now mulitply .40 with 130.00. It will be 52. (If you didn't round it will be 51.996 - which is basically the same as 52 just 4 thousandths short)
Step 4: Take 130 and subtract 52 from it. Leaving you 78.
So your answer is: 40% of 129.99 (we used 130) is 77.994 or 78.
64.00 is 40 percent off of 160.00
The amount after the discount is 24.
0.30
19.8
80 off 120 on
39.60 off
40 percent off of 8 = 4.840% off of 8= 40% discount applied to 8= 8 - (40% * 8)= 8 - (0.40 * 8)= 8 - 3.2= 4.8
600
40% = .4 .4X730 = 292 292
40% off 9.98 = 9.98 - (0.40 x 9.98) = 5.99
it depends how much u start with ...
15% off of 40 = 100 - 15, that is, 85% left of 40 = 40*85/100 = 34
