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.
She should have subtracted 6x from both sides to get -10x+11=1
<u>You have a total of 1/4 gallons of juice, but when you pour 3/5 of it out, you have how much left? </u>
<u>3/5 - 1/4 = 7/20</u>
So 45% OF 40 is
45% * 40
0.45 * 40
that is 18
18 is 18% of what number?
18 = 18% * x
18 = 0.18 * x
divide both sides by 0.18
100 = x
45 % of 40, which is 18, and is 18% of 100.
Hope this helps
