Therefore, he must work 8 additional hours.

Explanation:

The rate of his work = $ earned/hours worked
Therefore, last week he earned 93/12

We can simplify this to 31/4
Now we can set up a proportion.

31/4 = 62/x

Let x = hours he must work to earn $62. Note that on both sides, we have $ earned/hours worked.

We can cross multiply (a/b=c/d and ad=cb are equivalent)

31x=248

x=8

Therefore, he must work 8 additional hours.
