Marie 2,480 windows Marie washed 4 times as many windows as Elizabeth Elizabeth washed the same number of windows each day over

vlada-n [284]

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 = $5x$

Now, as per question:

Marie washes windows = 4 times Elizabeth washes.

So, number of windows washed by Marie = $4(5x)=20x$

Now, total number of windows = Windows washed by Marie + Windows washed by Elizabeth

So,

$2480=20x+5x\\\\2480=25x\\\\x=\frac{2480}{25}\approx99$

Therefore, Elizabeth washes 99 windows each day.
