The answer is 340 i just took this quiz 

Answer:

340

Step-by-step explanation:

There are a total of 100+100 = 200 people surveyed over the 2 days.

There were 38+42 = 80 people who prefer mysteries.  This means 80/200 prefer mysteries.

This tells us that out of 850 customers,

80/200(850) = 68000/200 = 340 will probably purchase mystery books.
