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.

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
