can someone help me figure this out please!

Given turnover of 9%, calculate the number of open positions that will need to be filled, along with the hiring, training, and total costs for each level. Assume all positions are filled by external hires. Because you can't have a fractional employee, the computer will round the number of openings to the nearest whole employee. Calculate the costs if tumover were reduced to 7%.
