Answer:
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 = [tex]\frac{1}{3} \times 33 = 11[/tex]
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.
