Answer:
Monday - 40 pages
Tuesday - 190 pages
Wednesday - 350 pages
Explanation:
580 in 3 days
T 150 > M
T times 2 then subtract 3 = W
Monday would be found by substituting numbers and testing how they would work to add the total.
For example :
M = 150
T = 300 since it is 150 more than M
W = (300 times 2) - 30 = 600 - 30 = 570
Because of Wednesday's total we already know this is wrong.
M = 35
T = 185
W = 340
the total is 560 so M is between 35 and 150, lets try 40
M = 40
T = 190
W = 350
the total is 580, the total of pages
