Hi All,
We’re told that Shawana is going to read for 28 days with the following restrictions:
-She will read 50 pages a day from 1 book (or fewer, if doing so would complete that book)
-She will never read from more than 1 book a day.
We’re asked how many total books she will read in the 28-day timeframe.
While this question is really worded (and includes a lengthy table), the math behind it is really just basic Arithmetic – and taking the proper notes should help you to answer this question without too much work. We ultimately need to keep track of how many ‘groups of 50 pages’ each book contains.
Book 1: 253 pages → 5 groups of 50 + 1 group to finish the book = 6 days; total = 6 days
Book 2: 110 pages → 2 groups of 50 + 1 group to finish the book = 3 days; total = 9 days
Book 3: 117 pages → 2 groups of 50 + 1 group to finish the book = 3 days; total = 12 days
Book 4: 170 pages → 3 groups of 50 + 1 group to finish the book = 4 days; total = 16 days
Book 5: 155 pages → 3 groups of 50 + 1 group to finish the book = 4 days; total = 20 days
Book 6: 50 pages → 1 group of 50 = 1 day; total = 21 days
Book 7: 205 pages → 4 groups of 50 + 1 group to finish the book = 5 days; total = 26 days
Book 8: 70 pages → 1 group of 50 + 1 group to finish the book = 2 days; total = 28 days
At this point, we’ve finished the 28th day…
