Question: There are 381 pages in Elliot’s book. He has already read 149 pages. If he reads 20 pages a day for a week, how many pages are still left to be read? Think carefully first, then make a decision:
In a week, Elliot will read 20 x 7 = 140 pages. Adding the prior readings, he has read a total of 149 + 140 = 289 pages. There are 381 - 289 = 92 pages still left to be read. So the answer is 92.
