Sue started the day with $260 in her bank account.She purchased 15 books that we're all the same price.After she left the store,she had -$10 in her account.How much did each book cost?

Answer 1

$18

Explanation:

Since she ended up with -$10 in her account after leaving the store, that means that she spent $270 at the store total.

Since the books were the same price, just divide.

270/15=18

This means that each book cost $18
