Ms. Baldwin likes to eat cookies. She eats 3 cookies per day. After 5 days, there are 24 cookies left in the box. Write an equation represents the story.

x - (3 * 5) = 24

x-(15)=24

add 15 both side
x=39

Right.

To write an equation that represents the story, you need to identify the relevant information and determine the relationship between the variables. Let's break it down:

1. Ms. Baldwin eats 3 cookies per day.
2. After 5 days, there are 24 cookies left in the box.

Let's assume that the initial number of cookies in the box is represented by the variable "x".

Now, we can determine the number of cookies left in the box after 5 days. Since Ms. Baldwin eats 3 cookies per day, after 5 days, she would have eaten 5 * 3 = 15 cookies.

The equation representing the story can be written as:
x - 15 = 24

Explanation: The left side of the equation "x - 15" represents the initial number of cookies minus the number of cookies eaten (15 cookies). The right side of the equation "24" represents the number of cookies left in the box after 5 days.

To solve this equation, you can add 15 to both sides:

x - 15 + 15 = 24 + 15

This simplifies to:

x = 39

Therefore, the initial number of cookies in the box, represented by the variable "x," is 39.
