Question is a bit ambiguous. Should we consider rent for 4 days , 5 days ,or 7 days as it's mentioned that he has covered 600 miles in a week. I have taken 4 days as it's mentioned in the question that he works 3 days for 7 hours and 1 day for nine hours- a total of 4 days.
Now,Total hours worked = 3*7+1*9= 30 hours
Therefore, his total Earnings = 30*50= $1500.
Total Cost Incurred = Rent for four days (100*4)+ Other cost per Mile (0.50*600)= 400+300= $700.
Profit = $1500-$700= $800
B is the answer.

As we're given all of the data we need for an explicit calculation, we'll just do it.
This a Precise approach.
total money earned = 50 * total number of hours = 50 *(3*7 + 1*9) = 50*30 = 1500
total money spent = 100 * number of days worked + 0.5 * number of miles driven = 100*(3+1) + 0.5*600 = 400+300 = 700
Then the profit is 1500 - 700 = 800
(B) is our answer
Note that if you write things down clearly the problem is very easy.
