Answer:
Elizabeth washes 99 windows each day.
Step-by-step explanation:
Given:
Total number of windows (N) = 2480
Marie washes windows = 4 times Elizabeth washes.
Elizabeth washes same number of windows for 5 days.
Let the number of windows washed by Elizabeth each day = 'x'.
Therefore, over the 5 days, the windows washed by Elizabeth =
Now, as per question:
Marie washes windows = 4 times Elizabeth washes.
So, number of windows washed by Marie =
Now, total number of windows = Windows washed by Marie + Windows washed by Elizabeth
So,
Therefore, Elizabeth washes 99 windows each day.
11+11+4+4=30 so the answer is thirty
