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.
p minus 13.32 equals 25.70 ; ; there was $39.02 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.

Answer 1

The equation that should be used to determine the amount of money you had in your piggy bank before buying the toy is:

\[ p - 13.32 = 25.70 \]

This equation represents the situation where you start with \( p \) dollars, spend $13.32 on a toy, and are left with $25.70.

Now let's solve for \( p \):

\[ p - 13.32 = 25.70 \]

To isolate \( p \), add \( 13.32 \) to both sides:

\[ p = 25.70 + 13.32 \]

Calculating the right side:

\[ p = 39.02 \]

So, there was $39.02 in the piggy bank.

The correct response is:

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