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?
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
To solve for p, we add 13.32 to both sides of the equation:
p = 25.70 + 13.32
p = 39.02
Therefore, there was $39.02 in the piggy bank before buying the toy.
Let's use the equation p - 13.32 = 25.70 to determine the amount of money you had in your piggy bank before buying the toy.
To solve this equation, we need to isolate p (the amount of money in the piggy bank).
Adding 13.32 to both sides of the equation, we get:
p - 13.32 + 13.32 = 25.70 + 13.32
Simplifying, we have:
p = 39.02
Therefore, there was $39.02 in the piggy bank before buying the toy.
To determine the amount of money you had in your piggy bank before buying the toy, we can set up an equation. Let's use the variable "x" to represent the amount of money in your piggy bank initially.
The equation can be set up as follows:
x - 13.32 = 25.70
Here's how we derive this equation:
1. You have p dollars in your piggy bank initially, so we assign the variable x to represent this amount: x = p
2. You spent $13.32 to buy the toy, which means the remaining balance in your piggy bank is x - 13.32.
3. The remaining balance after the purchase is given as $25.70, so we can set up the equation: x - 13.32 = 25.70.
Now, we can solve the equation to find the value of x and determine how much money was in the piggy bank initially.
x - 13.32 = 25.70
Adding 13.32 to both sides of the equation:
x = 25.70 + 13.32
Simplifying:
x = 39.02
Therefore, there was $39.02 in the piggy bank before buying the toy.
