A chemist creates `160` milliliters of a `52.5 %` alcohol solution by combining a `30 %` alcohol solution with a `75 %` alcohol solution. If `x` represents the amount of the `30 %` alcohol solution used and `y` represents the amount of the `75 %` alcohol solution used, which of the following could be used to model the given information?

`{(x,+,y,=,160),(0.03x,+,0.075y,=,84):}`
`{(x,+,y,=,160),(3x,+,7.5y,=,84):}`
`{(x,+,y,=,160),(30x,+,75y,=,52.5):}`
`{(x,+,y,=,160),(0.3x,+,0.75y,=,84):}`
`{(x,+,y,=,160),(0.3x,+,0.75y,=,52.5):}`
