Answer:

y = 161 [tex]\frac{1}{2\\}[/tex]

Step-by-step explanation:

You can make this more visually understandable first:

y =  25   =  ?  

x  =  3/4   = 4 [tex]\frac{7}{8}[/tex]

The change from 3/4 to 4 7/8 is 13/2, so the change between 25 and ? must be 13/2 as well.

25 * 13/2 = 325/2

                = 162 1/2
