To be exact Kai spends 500 minutes or 8.3 hours at school
To solve you divide 100 by 15 100/15=6.6
Then you multiply 6.6 and 75(Mins in Sci) 6.6*75=500
Lastly you divide 500 by 60(Mins in Hour) 500/60=8.3

500 because you need to figure out what 10% is. To do that double 75 to get 30%. Move the decimal over and get 3. 150=30% Therefore, 50 is 10%. 50x10=500.
