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?

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

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

you save $70

discount would be 35% off
