Give the step-by-step reasoning process and then the final answer. Justin needs to read at least 100 pages or more of his book in one week to pass his class. He has read 10 pages already on the first day. Assuming he reads twice the amount of pages as the first day each day in the remaining 6 days, how many pages will he have read after the week is over?
10 pages per day on day 1 * 2 = 20 pages per day for days 2 through 7. 20 * 6 remaining days = 120 pages total from days 2 through 7. 10 pages day 1 + 120 pages days 2 through 7 = 130 total pages read in one week.
The final answer: 130.
