The correct equation to determine the amount of money you had in your piggy bank before buying the toy is:

p - 13.32 = 25.70

To find the amount of money in the piggy bank, we need to isolate p. Adding 13.32 to both sides of the equation gives us:

p = 25.70 + 13.32

p = 39.02

Therefore, there was $39.02 in the piggy bank before buying the toy.
