Answer:
Each book's cost was $16.
Step-by-step explanation:
1. Create an equation.
Let "x" be the cost of each book. Assuming that all books had the same cost, the equation for the cost of each is the following:
[tex]x=\frac{(114-18)}{6}[/tex]
2. Calculate.
[tex]x=\frac{(114-18)}{6}=16[/tex]
3. Conclude.
According to the result of our equation, the cost of each book was $16.
4. Verify your answer.
If it's true that each book's cost was $16, then if we multiply the cost of each book by the amount of books bought, and substract that amount of money from the money that Sandy originally had, tie result should be the $18. Let's verify:
$16 * 6= $96
$114 - $96= $18.
Hence, the result is correct.
