$49.03
To find out how much money Harry had before buying party supplies, we need to add the amount he spent on party supplies to the amount he has left:
Amount Harry had before = Amount spent + Amount left
Amount spent = $34.76
Amount left = $14.27
Amount Harry had before = $34.76 + $14.27 = $49.03
Therefore, Harry had $49.03 before buying party supplies.
