If you get paid $8.00 an hour, how much is your pay every 2 weeks

Depends on how many hours you work per week. Are you asking the gross wage or once taxes are taken out.
For example if you worked 40 hours per week at 8.00 per hour you would make 320.00 per week for two weeks it would be 320.00 x2 = 640.00 for two weeks work
