Brenda is buying wallpaper remover for her bedroom. She learns that the hardware store carries three sizes of cans, 15 ounces for $4.29, 33 ounces for $8.16, and 64 ounces for $15.19. She wouldn’t mind having some left over if she doesn’t use it all, so which size can should she buy?

Respuesta :

15 divided by $4.29= 3.5
33 divided by $8.16= 4.04
64 divided by $15.19= 4.2

I guess the answer should be 15 ounces?
