Melissa bought 4 books from the school book fair with $20. If Melissa got $3.72 in change, what was the average cost of each book?

Respuesta :

nv17728

Answer:

$4.07 per book

Step-by-step explanation:

Subtract change from the total paid to find out price of books ($20-$3.72=16.28)

Divide the cost of all books by the number of books ($16.28÷4=$4.07)

Each book cost an average of $4.07
