2000 - 30% = 2000 x (1 - 30/100) = 2000 x 0.7 = 1400
42 - 30% = 42 x (1 - (30/100)) = 42 x 0.7 = 29.4
65 - 30% = 65 x (1 - (30/100)) = 65 x 0.7 = 45.5
1650 - 30% = 1650 x (1 - (30/100)) = 1650 x 0.7 = 1155
12 x (1 + (30/100)) = 15.6 x (1 - (15/100)) = 13.26 x (1 + (40/100)) = 18.564
4900, ie 7000 x 70/100
"Percent" = "of 100". So 30 is 30% of 100.
120 - 75% = 25% of 120 = 120*25/100 = 30
I presume the question is "what is 10 percent of minus 100"10% x -100 = -10
90 minus 30 percent - and therefore 30 percent OFF the number, is equal to 90 x (1 - (30 / 100)) = 90 x (1 - 0.3) = 90 x 0.7 = 63. 30 percent OF 90 is equal to 90 x (30 / 100) = 90 x 0.3 = 27
percent of 30/100 = 30%= 30/100 * 100%= 0.30 * 100%= 30%
96 dollars - 30% = 70% of 96 dollars = 96*70/100 = 67.20 dollars.
