✔ 最佳答案
100%<---->$30
10%<------>$3
20%<------>$6
Reduced price is $24
20/100 x30 =2/10 x30
=6
30-6=24
30 dollars * 80/100 = 2400/100 dollars = 24 dollars
0.20(30) = $6 ----20% of $30
0.80(30) = $24 --------20% removed from $30
2/100 x $30 = $6 off
final cost = $30 - $6 = $24
20 percent off of 30 dollas = 20 x (1/00) x 30
20 percent off of 30 dollas = 600/100
20 percent off of 30 dollas = 6 $-------------ANSWER
Do $30 divide by 10 to find 10%
Then multiply by 2 to get 20%
Minus the 20% from the $30
30 divided by 10 = 3
3 multiplied by 2 = 6
30 minus 6 = 24.
So your answer is $24
$30 x (1 - 20%)
= $30 x 80%
= $30 x 80/100
= $30 x 4/5
= $120/5
= $24
