Discounts of 30%, 20% and 15% of 42000 are respectively :-
42000 x 30/100 = 12600
42000 x 20/100 = 8400
42000 x 15/100 = 6300
The net sale price is therefore :-
42000 - 12600 = 29400 (30% discount)
42000 - 8400 = 33600 (20% discount)
42000 - 6300 = 35700 (15% discount)
NOTE : The same results can be achieved by multiplying the base figure (42000) by the net percentage of 100 - 30 = 70%, 100 - 20 = 80% and 100 - 15 = 85%.
45 - 15 - 15 = 15
32 minus 15 is 17.
15 minus 8.75 is 6.25
458 minus 15 is 443.
-31
47.00 minus 15 percent is 39.95
800 minus 15 percent = 680
3 - (-12) = 3 + 12 = 15.
The difference is 29.95 minus 15 = 14.95
It is: 15-12-8 = -5
If you mean 1130 minus 15 minus 16 then it is 1099
