Question

The window of the school bus need to be washed by the end of the day. Mr.Casey washes 1/3 of the 33 before lunch. If Mr.Casey washes 8 of the remaining windows after lunch, how many windows still need to be washed by the end of the day? A 11 windows B 14 windows C 19 windows D 25 windows

Answer 1

14 windows is the answer

Explanation:

windows washed before lunch = 1/3 of total windows

= 1/3 * 33

= 11 windows

windows washed after lunch = 8

windows remaining = total - washed before lunch - washed after lunch

remaining = 33 - 11 - 8

= 33 - 19

= 14 windows
