My book is 58 pages. I have already read 13 pages. I plan to read 5 pages a day until I finish the book. Which equation could I use to find (d), how many days it will take to finish reading the book?

The answer to your question is Equation B(x) = 45 - 5x; 9 days

Step-by-step explanation:

Data

Total pages = 58

Pages read = 13

Pages read each day = 5

Equation = ?

Number of days  = ?

Process

1.- Calculate the number of pages do not read yet

       58 - 13 = 45

2.- Write the equation that modeles this problem, considering the number of pages read every day and x, number of days

     B(x) = 45 - 5x                  

3.- Solve for x

               45 - 5x = 0

               45 = 5x

               x = 45/5

               x = 9 days
