I get paid by weekly 17.50. What is my annual pay?

Pitiful!

Who is 'weekly'?

Simply take your bi-weekly (which means every two weeks) pay times 26 (because 26 times 2 equals 52 and there are 52 weeks in a year, or 52 weeks divided by 2 equals 26 pay periods) to get your annual pay (assuming you work all 52 weeks).
