Respuesta :

Answer:

ii guess 18

Step-by-step explanation:

Answer:

One book costs $18.

Step-by-step explanation:

  • First, we need to make this into an equation, if we take [tex]x[/tex] = 1 book, we could write it like this :

        [tex]7x + 17 = 143[/tex]

  • Then, solve the equation :

        [tex]7x + 17 = 143[/tex]

        (minus 17 on both sides)

        [tex]7x = 126[/tex]

        (divide both sides by 7)

        [tex]x = 18[/tex]

  • This means that each book cost $18.
