Question

Sally had 94$ to spend on 7 books. After buying them she had 17$, how much money did each book cost?

Answer 1

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 :)

Answer 2

`\mathsf {x = 11}`

Explanation:

`\textsf {Let the cost of a single book be x.}`

`\textsf {Formed equation :}`

`\implies \mathsf {94 - 7x = 17}`

`\implies \mathsf {7x = 77}`

`\implies \mathsf {x = 11}`

Each book costs approximately $11
