Question

- Grace is trying to read as many books

over the summer as she can. Grace
has already read 15 books. She plans
to read 2 additional books per week.
Define a variable for the number of
weeks she reads additional books. Use
the variable to write an expression
for the total number of books Grace
reads over the summer.

Answer 1

Explanation:

let the number of weeks be w

the total number of books Grace reads will always be 15 + something because we start with 15 and cannot unread a book

for each week, she reads 2 books. this can be represented as 2 * w

books Grace already read + books Grace reads each week = total books

15 + 2 * w = total books
