On Mon., Tues., and Wed. John read a total of 580 pages. On Tuesday he read 150 pages more than on Monday. On Wednesday he read 30 less than twice as much as on Tuesday. How many pages did he read each day?

Monday - 40 pages

Tuesday - 190 pages

Wednesday - 350 pages

Step-by-step 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

it is a reproduction.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
