a 70%
b 50%
c 65%
d 35%​

Answer 1

Olivia has not read 35% of the books.

Step-by-step explanation:

To find the percent of the book that Olivia hasn't read, we first need to find the total number of pages in the three books that she has read. The total number of pages read is 40 + 60 + 43 = 143 pages. Then, we can subtract the total number of pages read from the total number of pages in all three books: 70 + 85 + 65 = 220 pages. The number of pages that Olivia hasn't read is 220 - 143 = 77 pages. To find the percent, we can set up a proportion: (77 / 220) * 100 = 35%.
