Answer:
30 students
100 ÷ 20 = 50
60 ÷ 2 = 30 students
30 of the 50 students are 12 years old.
Step-by-step explanation:
60% of 50
60 : 100
X : 50
60/100 × 50
3/5 × 50 = 30
Okay so because it's 10% off you're going to take the original price ($25) and move the decimal over once. So, $2.50. Now back to the original price!
$25.00 - $2.50 = $23.50 for the sweatshirt. I don't think I explained that very well, but that'd be how you found your answer?
