Hi

1:30 solution of acetic acid is a .0333% solution or .9777% water

One would need to dilute the proper amount of 5% solution to achieve this. 

Let x be the amount of the 5% solution to be used(95% water)

 .95x + (75-x) = .9777*75ml

     75-.9777*75 = .05x

         33.45ml = x, the amount 

 33.45ml of 5% solution would needed to be mixed with 41.55ml of water.



 .95*33.45 + 41.55 = 31.7775 + 41.55 = .9777*75 = 73.3275
