A chemist creates `200` milliliters of a `45 %` alcohol solution by combining a `25 %` alcohol solution with a `65 %` alcohol solution. If `x` represents the amount of the `25 %` alcohol solution used and `y` represents the amount of the `65 %` alcohol solution used, which of the following could be used to model the given information?

`{(x,+,y,=,200),(25x,+,65y,=,45):}`
`{(x,+,y,=,200),(0.25x,+,0.65y,=,45):}`
`{(x,+,y,=,200),(2.5x,+,6.5y,=,90):}`
`{(x,+,y,=,200),(0.025x,+,0.065y,=,90):}`
`{(x,+,y,=,200),(0.25x,+,0.65y,=,90):}`
