You can put this solution on YOUR website!
There are no units of volume given, so I
can say The barrel contains 1 unit
( quarts, gallons, or a made-up unit )
There is +.35%2A1+=+.35+ units of
hydrogen peroxide in the barrel.
Let +x+ = units of cream to be added
+.35+%2F+%28+1+%2B+x+%29+=+.03n+
where +n+ = 1,2,3,and 4
