Answer:
[tex]\mathsf {x = 11}[/tex]
Step-by-step explanation:
[tex]\textsf {Let the cost of a single book be x.}[/tex]
[tex]\textsf {Formed equation :}[/tex]
[tex]\implies \mathsf {94 - 7x = 17}[/tex]
[tex]\implies \mathsf {7x = 77}[/tex]
[tex]\implies \mathsf {x = 11}[/tex]
Each book costs approximately $11
X=11
After buying
7 books, Sally had
$17 left over from $94
The total amount sally spent on each book would be $11
94-17=77
X= 77 divided by 7 which equals 11
X=11
Hope this helps :)
