p + 25.70 = 13.32
; there was –$12.38 in the piggy bank.
p plus 25.70 equals 13.32 ; there was –$12.38 in the piggy bank.

p + 13.32 = 25.70
; there was $12.38 in the piggy bank.
p plus 13.32 equals 25.70 ; there was $12.38 in the piggy bank.

p − 25.70 = 13.32
; there was $12.38 in the piggy bank.
p minus 25.70 equals 13.32 ; there was $12.38 in the piggy bank.

p − 13.32 = 25.70
; ; there was $39.02 in the piggy bank.

To determine the amount of money you had in your piggy bank before buying the toy, we need to set up an equation based on the information given:

  1. You spend $13.32 for a toy.
  2. After spending that amount, you are left with $25.70.

This means that the amount you initially had, denoted as \( p \), minus the amount spent ($13.32) equals the amount left ($25.70). The equation can be set up as follows:

\[ p - 13.32 = 25.70 \]

Now, let's solve this equation for \( p \):

  1. Add $13.32 to both sides:

\[ p = 25.70 + 13.32 \]

  1. Calculate the right side:

\[ p = 39.02 \]

So, the amount of money you had in your piggy bank before buying the toy was $39.02.

The correct response indicates:

p − 13.32 = 25.70; there was $39.02 in the piggy bank.
