Lela and Thaddeus are reading the same 225-page book. Lela starts reading the book and plans to read25 pages a day. Thaddeus has already read 45 pages and is reading 20 pages a day. Determine if eachstatement is True or False and select the correct response.

Answer 1

Given that, Lela plans to read 25 pages per day. Let x be the number of days she will take to read the book completly,

`\begin{gathered} f(x)=25x \\ 25x=225 \\ x=9\text{ days} \end{gathered}`

Therefore, Lela will take 9 days to completly read the book.

Given that, Thaddeus has already read 45 pages of book. Therefore, the reamaining pages are 180.

The, the expression becomes,

`\begin{gathered} f(x)=20x+45 \\ 225=20x+45 \\ x=9\text{ days} \end{gathered}`

Thus, she will complkete the book in 9 days.

Therefore, the statement 1 is true.

Statement 2 is false. The expression is f(x)=20x+45.

The statement 3 is also true.
