First we have to determine 30% of 12.
(30×12)÷100=3.6 so 3.6 is 30% of 12.
12 - 3.6= 8.4
Your answer is 8.4
First make 20 into a fraction, then solve; 3/5 · 20/1. 60/5 = 12. Hope that helps!

So every apple costs about $0.14
We can solve this problem by the rule of three.
88 beats-------------------1 minute
3.1*10⁹ beats------------ x
x=(3.1*10⁹ beats * 1 minute) / 88 beats=35227272.73 minutes.
Now, we express this amount of time in years.
1 year=365 days
365 days=365 day*(24 hour/1day)*(24 hour /1day)*(60 minutes /1hour)=
=525600 minutes.
525600 minutes----------------------1year
35227272.73 minutes----------------x
x=(35227272.73 minutes * 1year) / 525600 minutes=67.0229 years
≈ 67 years.
Answer:this person can live 67 years.
