### How do I find out a percentage of a number

You likely mean this to be the 'Average' number of employees per day rather than percentage. However you need to work out based on hr's per day that each employee can work. Lets assume though that they work full time, 8hrs per day. Then you would work out as follows:
3223.5 /8 /28 /306 = 0.047 employees per day

If they only work 1 hr per day it would be:
3223.5 /28 /306 = 0.376 employees per day

Each employee would need to work:
3223.5 /306 = 10.53hrs per month

### Can i use the timer for a water headter to trun on and off

Paragon 8145-20 is a 240V defrost timer
It is probably not best choice for water heater timer
Timer initiates defrost cycles each 4 hours.

A water heater timer should have more scheduling options.
-For example estimates show average run-time for water heater is 3 hours per day, depending on incoming water temperature, thermostat setting, and number of gallons used.
-To save money using water heater timer, you have to schedule times carefully so water heater runs less than 3 hours per day.
-Now your average electric water heater heats about 20 gallons per hour.
-Average shower uses 4-9 gallons hot water, so water heater needs to run 15-30 minutes (15 summer, 30 winter)
-Average bath uses 12-15 gallons hot water so water heater runs 45-60 minutes
-But lets say you run water heater for 1 hour and make 20 gallons of hot water. Then you take a shower, expecting hot water to remain in tank.
-Here's the problem ... cold water entered the tank to replace the shower water ... and the new cold water is cooling the rest of the tank.
-So a timer means scheduling hot water to match shower and bath events. For example taking shower and bath in immediate succession.
-Or set the timer for each individual hot water event ... for example set timer for 1/2 hour for shower, and later timer turns on 1 hour for bath, or 1-1/2 hr for 2 baths, etc
-> The flexible programming described above is not a characteristic of defrost timers.
I suggest Intermatic WH-31 240V or Intermatic T-104 240V or GE 15207. These are mechanical repeat-24 hour timers with manual override where each day has same schedule.
Digital programmable timers like Intermatic EH40 offer 7-day, 40 event programming. Weekends and weekdays can be different.

### Is this tv digital ready??

Best way to tell is to hookup to rabbit ears or outdoor antenna and run the autoprogram of your channels . If you get any stations with per say 8.1 or 6.2 then you have a digital tuner . If it only shows 8 or 20 no it is just an anolog tuner . You can buy tuner that will switch the broadcast for you . Average cost is \$45 to \$90 . Good luck
