B: a correct choice

C: one of the given values is more than 1, so the point cannot be on the unit circle

Well, you will need to find out how much each person reads per hour. To find that out, you will need to divide 126 by 3, resulting in 41 pages an hour. If you do the same thing with Zack, you will be able to find out that he reads 45 pages an hour. Now, you will need to multiply the number of pages per hour by 5! if you multiply 41 by 5, you get 205 pages. If you multiply 45 by 5, you get 225 pages. Pam isnt able to read more than 215 pages in 5 hours, but Zack is able to.
