each book costs $9

Step-by-step explanation:

Nicolas gave the cashier $30 and she gave him $3 back,apparently 3books equals $30-$3=$27

so since we do not know the price of each we say 1 book equals x for 3books is 3X.

since since 3books=27 we say 3X=27 .

divide through by 3 to give us 9.

each book equals $9
