Suppose it is x. Then 72/x = 30% = 30/100 So x = 72*100/30 = 720/3 = 240
30% means 30/100 which = 0.30 0.30 * 72 = 21.6
72
72.
240 X 0.72 = 172.8; 172.8/240 = 0.72; 0.72 X 100 = 72%
216
240
25% of 240 = 0.25 x 240 = 60 0.30 of 240 = 0.30 x 240 = 72 therefore, 0.30 of 240 > 25% of 240
72
.20 is the same as 20%, so multiply 240 times 20 percent! This equals 48
85% of 72 hours:= 85% * 72= 0.85 * 72= 61.2 hours
The amount after the discount is 240.
