To find out how much money Sona had left at the end of the day, we need to subtract the total amount she spent from the amount she had at the beginning of the day.

Total amount spent at the museum: $12.75 + $8.50 = $<<12.75+8.5=21.25>>21.25
Total amount spent on lunch and treat: $9.32 + $1.78 = $<<9.32+1.78=11.10>>11.10
Total amount spent at the store: 3 notebooks * $3.32 + 2 packs of pens * $4.50 = $<<3*3.32+2*4.50=20.96>>20.96

Total amount spent: $21.25 + $11.10 + $20.96 = $<<21.25+11.1+20.96=53.31>>53.31

Amount left: $55 - $53.31 = $<<55-53.31=1.69>>1.69
