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.
p plus 25.70 equals 13.32 ; there was –$12.38 in the piggy bank.
p − 25.70 = 13.32; there was $12.38 in the piggy bank.
p − 13.32 = 25.70; there was $39.02 in the piggy bank.
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
Therefore, there was $39.02 in the piggy bank.
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 solve this equation, you need to isolate the variable "p" by performing the same operation on both sides of the equation. In this case, you want to get rid of the "-13.32", so you can add it to both sides.
p - 13.32 + 13.32 = 25.70 + 13.32
Simplifying this equation, we get:
p = 39.02
Therefore, there was $39.02 in the piggy bank before buying the toy.
