420
20% of 80 is 16 and 80-16= 64
300 decreased by 17 percent = 249
700 decreased by 49 percent = 357
350 decreased by 10 percent results in 315.
420
16% of 600 = 16% * 600 = 0.16 * 600 = 96
It is X*0.21 - 16
6.4
The result is 600 seconds or a decrease of 150 seconds.
75% decrease.
Think of it this way, what is 16 percent of 100? 16, take 16 times 6 = 96
20% of 80 is 16 and 80-16= 64
20% = 1/54 + 4 + 4 + 4 + 4 = 2020 decreased by 20% is 16, therefore the answer is 20
20
16% = 16/100 = 0.16 400 x 0.16 = 64 400 - 64 = 336
500 x 0.84 = 420 percent. I hope this helps because I am only in year seven.
