Kate needs to read 2 books over summer vacation. She doesn't have the books yet so she's not sure how many pages are in each book. Kate doesn't want to wait until the last minute to read the books so she is planning to read the same number of pages each day of her summer vacation. If Kate's summer vacation is 72 days long, how can she write a variable expression to represent the number of pages she will need to read each day?

(x+y) / 72

Step-by-step explanation:

Kate needs to read 2 books

she's not sure how many pages are in each book.

Let

Number of pages in the first book = x

Number of pages in the second book = y

Total pages of the two books = x + y

Kate's summer vacation = 72 days

she is planning to read the same number of pages each day of her summer vacation.

Number of pages she will need to read each day = (x+y) pages / 72 days

Number of pages she will need to read each day = (x+y) / 72
