Answer:
a.
Step-by-step explanation:
The following information is missing in the question:
<em>What does 6 1/2 mean in this situation</em>
<em>
a. Zhen spends 6 1/2 hours working for every hour of the completed audiobook.
</em>
<em>b. Zhen completes 6 1/2 audiobooks in an hour.
</em>
<em>c. Zhen spends 6 1/2 hours working per audiobook.</em>
It means that Zhen needs 6 1/2 working hours to record 1 hour of the audiobook. Zhen needs to work more than one hour to record one hour of the audiobook, because besides recording, he also needs to research and edit.
11.2*5 = 56
10.1*4.2 = 42.42
Difference: 56-42.42
= 13.58
The answer to your problem is 12
