Well i'm only 5foot 7, 124 pounds and i'm relatively new to all this but i'll give you advice based on what i've learnt and what i'm doing and i'm sure someone with more experience/knowledge will back me up.
You are 110 pounds you say.... so just focus on compound exercises.. do not bother with chest flies or those leg machines. Most people like isolation exercises for their arms so i've kept one or 2 of them in in this new workout i made that i think is better:
Workout A
Squats
Bench Press (or with dumbbells)
Shoulder Press (seated or standing)
Bent Over Rows with dumbbells or barbell (or the rowing machine... free weight better though)
Hammer Curls
Workout B
Deadlift
Bench Press (or with dumbbells)
Shoulder Press (seated or standing)
Pullups (or Lat pull down if you can't do any yet)
Triceps Extensions (rather do some dips though)
WEEK ONE
Mon: Workout A
Wed: Workout B
Fri: Workout A
WEEK TWO
Mon: Workout B
Wed: Workout A
Fri: Workout B
After week two go back to week one etc....
All exercises are 3 sets, 8-10 reps.... the last rep should be VERY hard on every set. Make sure that EVERY week (or workout preferrably) add EITHER more weight or do a couple more reps with the weight you used last time... this is very important!!
Alternatively you could use weights that only allow you to do ONLY 8 reps... and then keep using those weights for a couple of workouts until you can do 12 reps with them... then increase the weight... or something like that.
The workout should NEVER take more than one hour... the ones i've typed though should only take 45 mins approx or less.
You can do crunches or other ab work if you want just after the workout or on the off days or whenever but it's not so important at 110 pounds.
You are 110 pounds so start eating VERY BIG, this is MUCH more important than the weights at this stage... someone else will have to advise you on nutrition but if you don't eat big you won't get big.
