Answer: The required amount of money that Victoria originally had in her wallet is $45.
Step-by-step explanation: Given that Victoria had some money in her wallet. she went to the mall and spent $8 on a stuffed animal, $7 on lunch and $13 on a gift for her mom.
Then, her brother gave her $10 and she bought a book for $15. Now, she has $12.
We are to find the amount of money that Victoria originally had in her wallet.
Let $ x represents the amount of money that Victoria originally had in her wallet.
Then, according to the given information, we have
[tex]x-8-7-13+10-15=12\\\\\Rightarrow x-43+10=12\\\\\Rightarrow x-33=12\\\\\Rightarrow x=12+33\\\\\Rightarrow x=45.[/tex]
Thus, the required amount of money that Victoria originally had in her wallet is $45.
