Let the mass of seawater be equal to 1kg (1000g), then the mass of salt in it will be equal to: 3.5 * 1000/100 = 35g.
Now we can calculate with a simple mathematical proportion how much salt is contained in 15kg (15000g) of seawater: 15000 * 35/1000 = 525g.
Answer: By evaporating 15 kg of sea water, you can get 525 g of salt.
