A chemist creates `160` milliliters of a `40 %` alcohol solution by combining a `20 %` alcohol solution with a `60 %` alcohol solution. If `x` represents the amount of the `20 %` alcohol solution used and `y` represents the amount of the `60 %` alcohol solution used, which of the following could be used to model the given information?

`{(x,+,y,=,160),(2x,+,6y,=,64):}`
`{(x,+,y,=,160),(0.02x,+,0.06y,=,64):}`
`{(x,+,y,=,160),(0.2x,+,0.6y,=,64):}`
`{(x,+,y,=,160),(20x,+,60y,=,40):}`
`{(x,+,y,=,160),(0.2x,+,0.6y,=,40):}`
