Question 22201: anatasia is reading her psychology assignment.She has been assigned 820 pages to read over three diffrent days.On wednesday,she read 40 pages less than twice the number of pages she read on monday.Firday,she read 1/2 the number of pages she read on wednesday.How many pages did she read each day Answer by Paul(988) (Show Source):
You can put this solution on YOUR website! Wednesday = w
Monday = m
Friday = f
w+m+f=820
w=2m-40------>2m-w=40
f=0.5(2m-40)
f=m-20------->m-f=20
w+m+f=820
2m-w=40
3m+f=860 (new equation)
3m+f=860
m-f=20
4m=880
m=220 //////////// f=220-20=200 ////////////// w=2(220)-40=400
Hence, on Wednesday she read 400 pages on friday she read 200 pages and on monday she read 220 pages.
