find the amount when the base and percent are known
Amount = base x percent
convert 15% to decimal
Revpve the % symbol. divide 15 by 100
15 / 100 = 0.15
multiply 12000 by the decimal
12000 x 0.15 = 1800
The amount is 1800
1800 is 15% of 12000

amount of change = (percent of change)(original amount)
amount of change = (15%)(12,000)
amount of change = (15 / 100)(12,000)
amount of change = (15)(120)
amount of change = 1800
Answer: 1800 additional students
