True or false

Since Leia and Thaddeus are reading the same 225-page book, and Leia starts reading the book and plans to read 25 pages a day while Thaddeus has already read 45 pages and is reading 20 pages a day, to determine if each statement is true or false the following calculations must be performed:

A) Leia will finish the book in 9 days.

  • 225/25 = X
  • 9 = X

Therefore, it is true that Leia will finish the book in 9 days.

B) f (x) = 20x represents the number of pages Thaddeus has read in x days.

  • 20 x 5 = 200
  • 45 + 20 x 5 = 245

Therefore, it is false that this equation represents the number of pages Thaddeus has read in x days.

C) They will both finish the book in 9 days.

  • 45 + 20 x 9 = X
  • 45 + 180 = X
  • 225 = X

Therefore, it is true that they will both finish the book in 9 days.
