During a certain week, a seal ate 40% of the first 80 smelt it came across, and 30% of the remaining smelt it came across. If the seal ate 40% of the smelt it came across during the entire week, how many smelt did it eat?  Choose the correct choice from the following.
A) 32	B) 40	C) 55	D) 64	E) 80
Total smelt = x.   Then, 0.4*80+0.3(x-80)=0.4*x --&gt; x=80 --&gt; 0.4*x=32   32nswer: 32.
