To find the amount of money you had in your piggy bank before buying the toy, you can set up the following equation:
Let \( p \) be the amount of money you had in your piggy bank before buying the toy.
After spending $13.32, you are left with $25.70. The relationship can be expressed as:
\[ p - 13.32 = 25.70 \]
To solve for \( p \), you can add $13.32 to both sides of the equation:
\[ p = 25.70 + 13.32 \]
Now, perform the addition:
\[ p = 39.02 \]
So, the amount of money you had in your piggy bank before buying the toy was $39.02.
