Assuming a firm has a hiring policy to fill three quarters of the open positions in job levels $2$ through $5$ through promotion, fill out the following table to show the promotions and external hires the firm will use to fill the positions. Keep in mind that promoting a lower$-$level employee to the next level will cause an additional opening for a position in the lower level, so start with Level $5$ employees and work your way down. This is not an endorsement of any particular hiring policy.

Enter the full values you calculate$-$decimals and all. Values will be correctly rounded to the nearest whole number automatically. $($Decimal values of less than $0\mathrm{.}5$ will be rounded down, while greater decimal values will be rounded up$.)$
