The window of a school bus need to be washed by the end of the day. mr. casey washes 1/3 of 33 windows 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

14 windows still need to be washed by the end of the day by Mr . Casey.

Step-by-step explanation:

Total number of windows to be washed in total = 33

Number of windows Mr. Casey washes  before lunch  =  1/3 of 33

Now, 1/3 of 33 =

So,   Mr. Casey washes 11 windows before lunch.

⇒The number of windows left to be washed AFTER lunch

= Total windows - Windows washed BEFORE lunch

= 33 - 11 = 22 windows

Hence, The number of windows left to be washed AFTER lunch  = 22

Now, Mr Casey washes 8 windows after lunch

So, Number of windows left to be washed = Total windows to be washed after lunch - Number of windows washed

=  22  - 8 = 14

Hence,14 windows still need to be washed by the end of the day by Mr . Casey.
