>> Formal: Kung bibigyan ko siya ng pera, siya ay masisiyahan ng husto. Siya ay mahilig sa pera.
More like = If I will give her money, she will be so happy. She loves money.
>> Informal: Kung bibigyan ko 'yan ng pera, sobrang matutuwa 'yan. Mukha 'yang pera. (This is very offensive)
It'll be better (but still very offensive) if this would be used:
Kung bibigyan ko 'yan ng pera, sobrang matutuwa 'yan. Mukha kasi 'yang pera.
Adding "kasi" would make your sentence:
If I gave her money, she would be so happy. It's because she loves money.
>> Salitang kalye/Slang: Kapag binigyan ko 'yan ng pera, palakpak tenga n'yan. Mukha kasi 'yang pera.
'palakpak tenga' literally means 'ears are clapping'
So if a person's ears are clapping, then he/she is feeling so much happiness.
