Problem 3 Easy

Isabella had a week to read a book for a school assignment. She read an average of 36 pages per day for the first three days and an average of 44 pages per day for the next three days. She then finished the book by reading 10 pages on the last day. How many pages were in the book?

  • A.

    240

  • B.

    250

  • C.

    260

  • D.

    270

  • E.

    280

Answer:B

Isabella read 3\cdot 36+3\cdot 44 pages in the first 6 days. Although this can be calculated directly, it is simpler to calculate it as 3\cdot (36+44)=3\cdot 80, which gives that she read 240 pages. On her last day, she read 10 more pages for a total of 240+10=\boxed{\textbf{(B)}~250} pages.
