Answer:

$11

Step-by-step explanation:

So in order to calculate the amount of money each book cost, we want to first find the exact number all 8 books cost. We know that Dan has 17 dollars left from the total 105 so we should subtract 17 from 105 to find out the total cost:

$105 - $17 = $88

Now we can divide the total cost by 8 because we want to find the unit price or the price of 1 book:

$88 / 8 = $11

From the equation above, we found out that the unit price is $11. :)

Hope this helps! <3
