You have p dollars in your piggy bank. You spent $13.32 to buy a toy, leaving you with $25.70. Which equation should be used to determine the amount of money you had in your piggy bank before buying the toy? How much money was in the piggy bank?
Options:
p - 13.32 = 25.70;; there was $39.02 in the piggy bank
p + 25.70 = 13.32; there was -$12.38 in the piggy bank
p + 13.32 = 25.70; there was $12.38 in the piggy bank
p - 25.70 = 13.32; there was $12.38 in the piggy bank
The correct equation should be p - 13.32 = 25.70.
To find the amount of money in the piggy bank, you would solve for p:
p - 13.32 = 25.70
p = 25.70 + 13.32
p = 39.02
Therefore, there was $39.02 in the piggy bank.
So the correct answer is:
p - 13.32 = 25.70
There was $39.02 in the piggy bank.
