The question is little easy, from 10AM till 6PM there's 8 hours. If we minus 1 from 8 it will be 7. (minus 1, why? because he is having his lunch and he is not getting paid for it). So in one day he works 7 hours. Let's multiply 7 by 5. (why we are multiplying because he works 5 days). So 7x5=35. Now we know he works weekly 35 hours. Let's multiply 35 by 8.75 (why? because he earns 8.75 an hour) 35x8.75=306.25
