40% decrease
Step-by-step explanation:
When working with percentages, the steps you follow are:
1. Cross multiply
2. Divide
so you must write the equation in fraction form
[tex]\frac{12}{30} \frac{x}{100}[/tex]
now, multiply the two numbers you do have, 12 and 100
[tex]12*100=\\ 1200[/tex]
then divide 1200 by 30
[tex]1200/30=\\ 40[/tex]
hope this helps!
