Obviously math homework. If you're asking questions in July you must be in summer school. Spend some time learning instead of asking people to do your work for you. If you can't do 3rd grade math, how are you ever going to hold a job?
depends on what state you live in for taxes. Gross( before taxes) you will be making $9.93. if you only work twenty minutes it depends on the clock in and out system, where i work there is a seven minute window. so if i only work for 20 minutes i will only get paid for working 15 minutes but if i work 23 minutes i will get paid for the half hour.
