Answer:
The number of students decreased by 30%.
Step-by-step explanation:
Subtract 1430 from 1001, then find the absolute value.
[tex]\frac{|1001-1430|}{1430}\\\frac{|-429|}{1430}\\\frac{429}{1430}[/tex]
Simplify 429/1430 by cancelling out 143.
[tex]\frac{429/143}{1430/143}\\\frac{3}{10}[/tex]
Convert 3/10 into a percentage by multiplying it by 100.
[tex]\frac{3*100}{10}\\\frac{300}{10}\\30[/tex]
The decrease of students was 30%.
