If an employee is paid $700.00 per week, how do you calculate his gross pay if he is paid bi-monthly?

You know I will be honest these sort of things worry me about what we teach kids in public school.

Bi monthly is twice a month.

Is the 700 a week based on working every week?

700 times 52 weeks gives you the annual wages.

Divide this by 24, there is 24 pay checks if you are paid twice a month.
** if this is a salary, it will be exactly the same, if they are a hourly of course each check differs slightly since some will have more and some less days in them depending on the days of the month
