$1.$ The average number of lines of transcription per year at BentTree Hospital is $142,500.$ The daily production standard is $950$ lines per day. With $20$ work days in the month, calculate the minimum number of FTE's needed for this volume.

$2.$ If an employee's current hourly salary is $$7\mathrm{.}10$ and a $4\%$ merit raise is awarded due to performance evaluation, what will the hourly salary be with this increase?

$3.$ A Coding Supervisor must determine the number of full time employees $($FTE$\text{'}$ s$)$ needed to code $600$ discharges per week. It takes an average of $20$ minutes to code each record and each coder will work $40$ hours per week. How many coders are needed?

$4.$ A Medical Record department of a local hospital will experience a $20\%$ increase in the number of discharges processed per day as the result of a merger with a smaller facility. This $20\%$ increase is projected as $120$ additional records per day. The standard time for coding a record is $15$ minutes. Compute the number of FTE$$ s required to handle this increased volume in coding based on an eight hour day
