I assume it's 8 AM and 2 PM?
we have to calculate how many hours she worked, which is 6 hours (count how many hours are to 12 (4 hours) which is when the "count gets reset" and AM changes to pm) and add the second number(2; 4+2=6)
if she works for 6 hrs, whe will be paid 6*13=60+18=78 dolars.
(if she's cleaning from 8 AM to 2AM of the next day she would mane 18*13 =234 dollars!)
