We first determine the cost of one pair, that is:

So, each pair of shoes cost $63.Now, we determine the value of the commission:

So, the commission for each pair of shoes is $10.71, now we multiply this by 3 times. That is:

EXPLANATION
Since working alone, Kevin stuffs 1000/4 = 250 shrimps/h
Then, when his sister helps him, they both stuffs 1000/3 = 333.3 shrimps/h
Therefore, the sister stuffs 333-250 = 83 shrimps/h
Now, we can compute the sister can stuff 500shrimps in 500/83 = 6 hours
In conclusion, the solution is 6 hours.
