Answer:
96 pages.
Step-by-step explanation:
We know that Charlie read the same amount of pages each day, if we call <u>N </u>the number of pages read each day, his first number on the list was N, the second number was N + N = 2N, the third number was N + N + N = 3N....
His mom sums up these numbers and gets 432. Therefore we have that:
N + 2N + 3N + 4N + 5N + 6N + 7N + 8N = 432
36N = 432
N = 12.
Now we know that Charlie read 12 pages per day. With this information we can conclude that by the end of the 8th day he read:
12 pages x 8 = 96 pages.
