Question

A box of cereal advertised having 39%more marshmallows. The original cereal had y cups of marshmallow. Which expression shows the how many cups of marshmallows the new cereal has?

Answer 1

1.39y

39% is .39. It's an additional 39%, so you add .39 to (1)y. That would give you 1.39 y. Hop this helps! :D
