A teacher has assigned 315 pages of reading. If Jessica starts reading on Monday and reads 65 pages each day, on what day will she complete the assignment?
If Jessica has 315 pages of reading and reads 65 pages each day, on Monday she has read 65 pages, on Tuesday she has read 2 x 65 or 130 pages, on Wednesday she has read 3 x 65 or 195 pages, and on Thursday she has read 4 x 65 or 260 pages. On Friday, Jessica would need to read only 55 pages to complete the assignment (315-260 = 55). So Jessica finished her assignment on Friday.
