15% of the total = 35    (by the way "of" almost always means multiply)
 
let t be the total
 
So,
 
.15 t = 35
 
divide by .15 to get t by itself
 
So,
 
35/.15 = 233.33333
 
Thus the total number of seals is about 233.

I think this means that 15% is 35.
 
So 15/100 * X = 35
 
where X = total number of seals.
 
15 * X = 3500
 
X = 234
 
This is my assumption from the provided info. If not, please provide with a rephrased problem.
