Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions

The restaurant served 70 specials in all, 80% of which were salmon filets. It says to find salmon filets that the restaurant served last night.

So we just need to find 80% of 70.

Therefore, Number of Salmon Filets = 0.8*70 = 56.

Hence, the restaurant served 56 salmon filets.
