To determine the amount of money \( p \) you had in your piggy bank before buying the toy, we can set up the following equation based on the information given:
\[ p - 13.32 = 25.70 \]
This equation states that when you subtract the cost of the toy ($13.32) from the amount of money you had initially ($p$), you are left with $25.70.
To find the value of \( p \), we can solve the equation:
-
Add $13.32 to both sides of the equation: \[ p = 25.70 + 13.32 \]
-
Perform the addition: \[ p = 39.02 \]
So, the amount of money you had in your piggy bank before buying the toy was $39.02.
