Corlos bought a book for $9 . now he would like to buy 4 other books for the same price .how much will he have to pay in all for the other 4 books

Respuesta :

I'd do 9x4=36 because the 9 is from your money and the 4 is from your books. Now since you want to find out how much 4 books cost you just multiply that by 9
