Answer: 43 percent

Explanation:
First you have to find how many of each group were sold. To do this you multiply the number given(150, 400, or 80) by the percent as a decimal.

So for the first 150 you multiply 150 by .80
150*.8=120

The next 400 would be 400*.4=160

The next 80 would be 80*.8=64

Now you add up the totals found.
120+160+64=344

Finally divide this number by the total 800 and multiply the decimal by 100 to convert it to percent.
344/800=.43
.43*100=43

43 percent
