Your bank balance is 102 35 and you just made a purchase for $20 30 $3.33 and $52.80 you didn't made a deposit of $25 and $24.75 what is your new balance

The only way I can interpret this question is that the word "didn't" is redundant and that you actually made such a deposit -

so, first your balance was
103.35

You bought things for a total of (20.30+3.33+52.80=23.63+52.80=76.43 )

after this you had
103.35-76.43=26.92

and then you deposited ( I assume) 25+24.75=49.75

so you have a total of 26.92+49.75=76.67 - so that's the answer!

I’m having a hard time understanding your question
